Post your Highest OC'

[yfital]

hmm, got my 4400 to 2.65 with normal vcore (~1.48), didnt oc it yet on my expert as it is dead ;\

got my ram to ddr500 @ 2-2-2-0,1t, and everything else on tightest on the expert, was truly fun ;} only took 3.4 vdimm, the ocz's gold vx are freaking sweeT!

[Jigar]

Ok great machines i see over here although i have a rocket which is 2.2GhZ at stock speed & which i have OC to woping 3.0 GHZ and DDR400 is OC till 550 MHZ..... What do u say friends..... And i have made a home made watercooling system with Internal mositurless AC (airconditioner).. to keep the beast cool.

Yeah, the VX dimms rock! I heard great things about them, almost bought them my self, but there's no 1GB dimms for it so thats a no go for me I guess ... But very nice OC! .

[yfital]

its still not complete as my board died from running sandra (dont ask, dfi did a nono ;\)

but for a 3200chip its very nice indeed, though they aint that cheap...
i wish i would have waited and got the ones with the other heat sinks, they look cooooool |:

My highest ever, X2 3800+ at 2.75ghz.

This thread has been resurrected. lol

P4 3.0E @ 3.8 GHz on Gigabyte 8KXNP rev 1 (but used BIOS rev 2)
Kingston KVR ram 2x 512 MB.

But it's history. Now I'm on C2D E4500 and don't OC.

[MaxTheLimit]

Well my highest OC was with my E6300. Over3.5GHz. That only runs in the winter though. 3.4 is what I run 24/7. Sill 1.86 -> 3.4 is an 86% overclock. Not too shabby I'd say.

[bthylafh]

My 1998 vintage ATI Xpert@play 8MB RagePro graphics card from 75MHz to 103MHz

and it was still crap

I briefly oc'd an i740-based card by switching the AGP 2x slot from 66 MHz to 100 MHz[1]. I didn't notice much of a difference in Half-Life and the card didn't last long.

[1] I don't know why you could do that either. Ask whoever designed the BH6 motherboard.

I can barely get my E4400 to post at 3.4ghz.

I think the only thing I've ever overclocked 100% was my old Diamond Stealth II S220. Seeing as it didn't have a heatsink I glued an aluminum pencil sharpener to it and overclocked it from 40mhz to 80mhz.

[Hance]

Some processors do good and some dont. I picked up a e2140 for my wife awhile back and it sucks in the overclocking department. 2.8 ghz is all it can do. That overclock was with my proven memory and motherboard so I know it was the processor. I had always planned on running it at stock speeds but wanted to see how high it would go. It was nothing to get excited over thats for sure.

[enzia35]

Got my 3600+ x2 from 1.9ghz to 2.77ghz. It's about at it's end too.

[Crayon Shin Chan]

Celeron 600 at 675Mhz. Yes, pathetic, I know.
second best: AXP 1800+ (slightly unstable at 1900+ speeds, stupid Thoroughbred-A)
DDR RAM on my Ti4200 card (50MHz more, not counting DDR)

I picked up a e2140 for my wife awhile back and it sucks in the overclocking department. 2.8 ghz is all it can do.

I decided to buy an E2180 thinking 3000mhz would be decent given the cost and it would make a good stand by until the 45nm parts arrive but after 3000mhz for 2 months and never feeling near as fast as my E6600 at stock let alone 3000mhz or the 3600mhz I was running it at........ an idiot recommends I use Intel's TaT to test it which promptly overheats it badly each time I'm using it, I've got a good water cooling and at the time am confused but check and recheck the seat after changing the past and making sure on pump rpm... according to TaT 2100mhz was all my cpu should have gotten before burning a hole to china....... so I mention I believe the app is garbage and something is wrong but I didn't do any research and idiot claims he has and stands by his comment "it's an official Intel benchmark and diagnostic app".....after toasting my dual core for another day I delete the app but upon restarting the computer it suddenly won't post any higher than 2600mhz..... within 2 days it's dropped to 2200mhz and now I'm stuck at 2000mhz not entirely stable......I intend to unplug the pump given it was an Intel app that killed my cpu it's their dime and no I'm not concerned and no my conscience is clean on the matter, just waiting for the 2nd system to be built.

prior to said 2180 I've had.

Intel 2.4 non HT overclocked stable on water at 4210mhz for 2 months before sold insanely fast at the time.... lI took two 2.4's up to 4000+ mhz one to the previous mentioned and the 2nd to a stable 4121mhz both are still running to this day but at stock speeds, 1 motherboard died though.

E6600 running 3600mhz daily for 3 months before I sold it but it wasn't 100% and occasionally would crash... about 2 X a week likely due to my own personal voltage restriction I believe it had stability in it but was worried about longevity voltage was at 1.425.

2500+ mobile socket at running 2500mhz stable on water stable.... I assume it's still running to this day at stock speeds somewhere.

Opteron 170 dual core (2000mhz) 2800mhz stable at 1.4 volts undervolted cpu with Mushkin 500mhz Redline ram.... it was fast "enough" even by todays standards but the grass is always greener and I wanted 3000+mhz which Intel was able to offer first, cpu and motherboard are still running to this day at stock with stock cooler re attached........ ram has since been sold.

[Jigar]

1) 3200+ Athlon 64 @ 3.0 GHZ (Max went till 3.2GHZ stable, was a bit unstable @ 3.3GHZ) with Water cooling and AC cooling.

2) 4400+ X2 Atlon 64 @ 3.4 GHZ (Max went till 3.8 GHZ but unstable above 3.4GHZ) with LN2. (Home made)

3) Q6600 @ 3.2 GHZ (Max went till 3.9 GHZ unstable, stable till 3.65 GHZ but temperature goes very high without extra cooling and now i don't have LN2 any more )

4) XDA O2 Atom @ 624MHZ (actuall speed 416MHZ) this PDA is rock solid for daily task and phoning but becomes a power hog, once overclocked.

[asafley]

As of right now I have my loyal Pentium D 930 (which if I would have known about the Core 2 Duo a couple of months earlier I wouldnt have bought the PD ) overclocked to 3.69 GHz stable from 3.0 GHz. This is so far my best OC since I cant overclock my little server which is running at 2.7 GHz and is idling at 46 C and under load it reaches about low 80s. My ultimate goal for my PD was to reach 3.8 GHz but after ~3.7 it just yells at me; The voice from within the PD yells, "Are you freaking kidding me? I ain't going to run at that speed!" But anyway, It runs about 36 C idle and reaches about high 40s to low 50s C after playing Crysis on my SWEET 7600 GT .

TAT is one of the most stressful apps that one can use for an Intel CPU. This means your OC does not really hold even you think it does. Also, it does not feel as fast probably because of the trimmed L2. Xbitlabs did a test and the drop off from E6K to E4K is ok, but the drop off from E4K to E2K is not. In your case going from E6K to E2K of course is going to be significant.

I no longer have that setup because I moved that chip onto a P965 for a HTPC setup. If I recall correctly, I believe I had the vcore at about 1.36 or 1.37 and added .1 to the FSB.

TAT is one of the most stressful apps that one can use for an Intel CPU. This means your OC does not really hold even you think it does.

the problem here is relevance and having done some research on my own I've found out that TaT is virtually worthless having been developed for mobile cpu's it's temp indications are fundamentally flawed and the synthetic load test seems dubious at best.

1st I ran the 2180 at 3000mhz and played BioShock from Start to Finnish, I played Half Life 2 the entire series from start to finnish, I burned and decoded numerous DVD's, burned files like crazy, did file transfers, benchmarked the system extensively........ I did everything that ppl usually do when using their computer with gaming obviously being the most demanding although DVD decryption is usually somewhat stressful and for months the system was fine no hiccups, no pauses, nothing .... p.s. I knew ahead of time the cut down cache would hinder performance but I was expecting more and the cpu was never what I would have considered a good value to me.

anyway so I'm living with this cpu and I'm introduced to Intel's TaT application.

running the cpu's at TaT's 100% immediately shoots them to an indicated 85c and they clock throttled........ even running the cpu's at 50% resulted in eventual overheats and clock throttling....... this from cpu's that were powering a system under all sorts of real world loads and ran without a hiccup........50% load is too much by far and BioShock or Half Life 2 gaming for 3+ hours doesn't load the cpu more than TaT in less than 2 minutes?...... I'm not saying they weren't being stressed but I am saying what is TaT doing to kill these cpu's like nothing else can....(no question mark it's rhetorical)... and not just somewhat more but the synthetic results didn't reflect real world useage nor even remotely come close..... additionally understand I'm using a PolarFlo water cooling system with dbl 120mm fanned radiator and swiftech water pump..... this same cooling setup kept an Intel P4 running 4200+mhz under 55c, an opteron dual core running 2800mhz under 53c under full "real world" load for both..... in the case of the Opteron I burned 9 DVD's in 2 hrs while gaming as much as I could while running WMP, while websurfing, while doing a 9gb File transfer trying to punish the system as it was my fist dual core..... it had 2LG DVD+-RW's, 2gb's of ram and Striped Raptors which I'm sure helped.

anyway so I figure "well let's see what TaT say's I can do for an overclock without overheating?"..... the results 2100mhz... yes folks TaT would overheat the 2180 when under it's 100% load even with water cooling if left running long enough even at a meager 100mhz overclock and what made me consider even more was that without a doubt my cooling system was far more efficient than the stock Intel heatsink... this made me question whether TaT had any value at all but sadly by then it was too late and the damage was done.

to me TaT is entirely worthless given the 2180 would have overheated at it's stock 2000mhz with the stock heatsink had I used the tool making it worthless...... punishing the cpu to gain information is something, TaT isn't IMHO.

[Nitrodist]

Ok, so you ran some "benchmarks", played HL2, transferred files, ripped DVDs, burned DVDs, played BioShock.... do you realize that all of these don't stress the CPU to 100%?

[MaxTheLimit]

Well more and more applications are able to utilize the multiple cores. So you are going to be able to get more out of your CPU in instances where the whole CPU is utilized, BUT it also stresses the CPU more. That is one of the key reasons I like to make sure my CPU can run through brutal CPU stress testing, so I'm not riddled with blue screens.

How does your CPU fare with two instances of Prime 95 running?

Myself when I'm stress testing my cpu I run two instances (or 4 depending on the number of cores) on small fft's for at least 10 hours. if it passes with no errors and temperatures I can accept I run through memtest. If this passes I do a blend to get a little bit of everything and if it passes this I loop a stressful game for a good 8 hours to see if it's stable for that. Only after that do I declare a system stable to myself.

I hate blue screens and running my system in a set up that is going to cause problems for me later. I really do recommend this as I see no ill effect of running my system at the over 85% it is now. Plus I feel confident when programs come out that may stress my CPU or system more I will still have no problems.

Very much worth it I'd say.

Keep in mind that not all "CPU at 100%" is created equal. This has been explained even back in the days of CPUburn (a while back) where they would exercise the FPU more for the most intensive instructions that can generate the most heat. Just games and DVD decrypt is not that stressful enough for me. Prime95/Orthos, Folding, OCCT and TAT are the ones that really give the CPUs a workout.

It's really up to your tolerance level in the end I guess. There may be a slight chance with some random errors if you don't use those really "high end" stress programs to really stress the CPU. To call it "worthless" is a quite a stretch, TAT's temperature reporting may be wrong because of the changing Tjmax, but that's because it was rather old.

Your set of applications is dubious to me as to whether they really stress the CPU to the max. Games in particular stress the GPU more than the CPU.

[MixedPower]

I'm currently running my E2140 at 2.8 GHz. For a while I thought it was stable at 3 GHz, but I ran Prime95 for ten hours and got an error on one of the cores a few minutes before It finished.

[Hance]

That is still a pretty good overclock. Anytime you are in the 50% range for an overclock you are doing pretty well in my opinion.

[clone]

so you ran some "benchmarks", played HL2, transferred files, ripped DVDs, burned DVDs, played BioShock.... do you realize that all of these don't stress the CPU to 100%?

sigh.....usually it's a little stressfull when your running a few of them simultanious while you wait for results from one app or another.

the problem here is relevance

1st I ran the 2180 at 3000mhz and played BioShock from Start to Finnish, I played Half Life 2 the entire series from start to finnish, I burned and decoded numerous DVD's, burned files like crazy, did file transfers, benchmarked the system extensively

Intel's TaT seems to be the only problem...... does that make TaT matter?..... to me no, that TaT wouldn't allow me to overclock more than 100mhz while every other app is good with it..... does that make TaT matter?..... to me no.

IMHO TaT's worthless.

note the IMHO, it's like basing my computers overclock on running Prime 95...... if it's 100% stable at everything except Prime 95 do I really care all that much?

I run it to test and then consider the results as a possible issue but I usually run my overclocks higher and if I run into an issue then I go with "well Prime 95 told me it would be an issue"... the problem with TaT for me is that a 100mhz being a possible issue really hurts it's value in my eyes when it's the only application showing any potential problem.
