SB Overclocking results?

Guess this is all the excite we get until socket 2011 gets here. Glad I fought the upgrade urge this time.

Still seem like nice processors for the money though.

Don't worry Filter, when my new case fans arrive I'll be on 4.9 (I really want 5).

I was only planning to have 4.6-4.7, but I reckon I can have this machine generate 50k ppd - so that is my new goal.
 
cant wait for my 2600k to arrive so i can add it to my folding farm. hoping for a modest 4.6ghz o/c on it.

I didn't read much hype that guaranteed 4.9GHz on air - most of the stuff I read was 4.8GHz was very doable and 4.4 to 4.5GHz was pretty much guaranteed . . . which is exactly what most have found so I don't know what the problem is.

I had a great overclocking 920 D0 that did 4.2GHz on 1.25v so I didn't "need" to upgrade but given that I was able to resell my old CPU & mobo and break even for my SB build, why the hell wouldn't I do it? SB overclocking is ridiculous easily (literally about 3 or 4 settings changes in the BIOS) and you're guaranteed at least 4.5GHz on just about every chip out there and last I checked, 4.8GHz still beats my former 4.2GHz.

You have a nice CPU and a nice OC on it but it seems like you're trying to justify the $1000 you spent on it by insinuating that SB isn't worthwhile because they all can't go 4.9GHz+ on air? The fact of the matter is your CPU is still great depending on the applications you need it for - but the vast majority of folks don't spend $1000 for their CPU. For the rest of the computing public, a $300 processor that does 4.5GHz to 4.8GHz (and SOMETIMES 5.0GHz) with only a handful of BIOS settings changes is pretty awesome.

Edit: I didn't see in your later post that you've also got a 2600k enroute - so my comments on your justification of the 980x may not be valid - but rest of my post above still applies.

I want to give you guys a heads up. My 2500k really increased my triple monitor performance. The lowest I saw bc2 dip was into the high 80s in 5760x1200 on high.
I was having trouble with it dropping into the 50s before and anything under 60 feels like ass on sli.

Arma 2 actually feels playable in 5760x1200 now.

That was coming from a 4ghz i5 760 with 470s oc'd to 800.
 
Pretty happy with my results so far... Quite an upgrade from the E4500 =)

Asus p8p67, 2500k, Corsair A70 Cooler, very well ventilated case

4.6Ghz prime stable, 1.3V, 57C at load

4.8Ghz prime stable, 1.35 Volts, 1.15V VCCIO, 1.15 VCCSA, 68C at load

4.9Ghz unsuccessful at 1.38V... Not willing to go much higher until the impact of higher voltages on these CPUs is better know...
 
2500k @ 4.7GHz with 1.36 volts. Using my trusty Ultra-120 after 8+ hours of prime it gets a little toasty at 75-78C. Playing BFBC2 or SC2 for a couple hours it doesn't go higher than 65C.

This is coming from a 4300 core 2 duo at 2.7Ghz and a x1950 pro so needless to say I am thoroughly impressed :D
 
2600k on P67 Pro. Temps achieved using IntelBurnTest.

4.6 @ 1.28 -- 55C Load
4.7 @ 1.31 -- 59C Load
4.8 @ 1.34 -- 63C Load


Have it sitting at 4.6 right now. Cinebench is over 9 @ 4.6. 4.8 or 4.9 feels very achievable 24/7 on air if I don't mind mid to high 60's temps.

lol i was commenting on all the pre hype of this chip and claims by some forum members it was going to do 4.9ghz and higher on air and it was the 2nd coming of jesus. i guess you missed all the pre game hype.

Seems like it has lived up to the hype to me. Guys on Xtremesystems running them over 5ghz on quality ( see loud ) air setups. On water and phase the chips are doing great as well. Some chips are better than others.

Considering you can be a complete moron and still overclock the chip to 4.5+ is proof enough of that.

and there is an amd doing 6.6ghz. doesn't mean the majority of users are getting 4.9ghz like people were claiming. .

You are like a broken record man. Give it a rest already. You obviously bought into the hype because you already bought a 2600K and you just bought that 980X like a month or two ago. When I read that thread, you were arguing about justification on your choice to buy a 980X or something like that. Now we need to argue about why our $300 procs are only pulling 4.6 - 4.8 on air instead of 4.9. Who fucking cares? 1ghz+ over stock is pretty fucking impressive and not really worth bitching about. Just let it go and relax a bit. Try to enjoy your new hardware for a while.

i have a 1ghz o/c on my q9300. have over a 1ghz o/c on my 980x . almost had a 1ghz o/c on my old 2500 barton. so it's really not that impressive

2600k is not a replacement to my980x its just an addition to my folding farm.

only reason i was justifying cause people were attacking it and making SB seem like its this super chip that can do 4.9ghz on air etc. and from what im seeing its not.
 
My 2500K is hitting 4.7ghz with the voltage set to auto (1.392-1.4v). Seems like it tops off at 75 C with my TRUE hsf

Pretty happy with this for the time being. 5.0 would be a nice psychological number to hit, but I doubt there would be any noticeable increase in performance.

EDIT: Changed the fan orientation around today. Temps now peak at about 66.

I forgot you were the guy whining about your 980x. Makes sense now.

how was i whining? casue i was letting people know that the 2600k wasnt a 2nd coming of jesus like alot of people were claiming it was. One of the things they were touting was 4.9ghz on air. I just want to know where these people are at.

my 2600k should be here wed to power my gpu farm and do smp folding.
 
Wow get over it already. The pre release hype for SB was purely that it's a great overclocker and it has lived up to that and then some.

Just because you read one or two people who claimed it could easily hit 4.9 on air doesn't mean thats what we all expected. All of your posts have seemed pretty hostile/defensive.. whats your problem?

It is a great chip for the price. That is why it is touted as the second coming. Being able to overclock has been the norm for many chips. My Q6600 OC'd well and I have no doubt my 2600k will, as well. It is the price to performance ratio that makes SB so nice. I can game on this for at least 2 years without upgrading and probably longer.

It is the graphics cards that need more attention.
 
Is there really much point to overclocking these SB chips? My 2600K stock turbo's up to 4450MHz with no adjustment. If I manually overclock it, I'll be looking at what 4600 maybe 4700MHz? These things are wicked as is.

A stock 2600K only goes up to 3.8GHz. Did you use the auto-tune or something?

Nope....stock p8p67 deluxe, stock BIOS settings. CMOS cleared everything in BIOS completely stock, only thing I've done is update to the latest 1053 BIOS.
 
Im at 4.3 with 1.3 so far. Just started playing with the overclocking. My load temps are at around 69-70c. Is that too high?

I used the stock cooler for about 1 day and noticed it sucked big time as I hit like 90c's on load with that thing. I went to bestbuy to see if I could find something decent and I found a corsair A70 cooler on sale for like $35. Although I can only use one fan at the moment cuz it seems like the ram blocks the other fan, I didnt try to hard to get it on though.,..
 
Running 6.2 gigahertz but had to increase the voltage to 120 volts. I find that alternating current really inspires the chip to do some manual labor. Temperatures were around 140 C. after I got the fire extinguished.

You should not need 1.3v for 4.3. 1.3v is good for 4.6 or 4.7 honestly. 69-70C is very high for that overclock, but not absolutely terrible for those volts.

If you are running higher than 3.8 you hit an auto tune button somewhere.

I'll try dropping my volts down, or maybe go higher in the o/c. I'll probably try resetting my HSF also. I wasnt to happy about how much thermal compound i had put on there.
 
finally got some new thermal compound (ic diamond) today in the mail.. no rush, taking it nice and slow and getting my 10 work units done so the bonuses start. Primes at 57 degrees or so.. everything at auto except manual adjustment to voltage offset of +.005. Happy enough with it in the 4.4 to 4.6 area, don't want to roast it just for a little more. Will try 4.5 in the morning after a night of folding.

Seems Prime95 Small FTTs is especially hard on these chips. I am Windows stable at 4.8 at 1.35V, and can run SuperPI and Intel BurnTest at those volts just fine, but Prime95 small FTT fails in mere seconds. Ran it up to 1.4V and still no dice on Prime95. It was stable at 5.0 at 1.5V, but I was hoping for a slightly lower speed at significantly reduced volts - guess that isn't happening.

Same here I can run IntelBurn Test for three hours (didn't try more) but Prime95 Small FTTs crashes after half an hour. I'm still going to leave it at 4.8GHz though. Running [email protected].

I'm wondering if I need to play with some other voltages. Doesn't seem like it should take much to go from IBT stable to Prime95 stable. Maybe something other than Vcore is the culprit.
 
LinX and Prime95 stresses the CPU much more. Comparing the two, I notice LinX is better. If you can complete 20+ runs with LinX, your CPU is very stable.

Aren't LinX and IntelBurnTest the same? Both are just front-ends for Linpack, right?
 
Well I enabled PLL overvoltage on my MSI board and was able to boot my 2600k at 5ghz with 1.46v. Ran some super pi, prime, and played bc2 all night long and it took it just fine. Load temps maxed at 70C - a little too hot for my taste so I bumped it back down to 4.8 for the time being. This chip is a beast.
 
Anyone playing with any of the other voltages (Vtt, Vccsa)? Seems strange that I can run 20+ LinX or IBT runs with no problems, but fail immediately with Prime95. Wondering if one of the other voltages might be a factor for Prime95.

Edit: Well, well, seems they do have an impact. Took my LinX/IBT stable but Prime95 failing 4.8 settings and bumped the Vtt and Vccsa a notch each, and it is happily crunching away at Prime95 30 minutes later, with both Small FTT and Large FTTs (both of which failed in about 5 minutes previously). So now, more clocks, or lower voltages?

If Prime95 crashes, you're not stable. You won't notice a 100 MHz drop but you will notice if your system bombs during something important.

It's not strange at all. According to folks at XS, Prime95 stresses different parts of the CPU so everyone's understanding of stability testing has to change for SB.

Anyway, I think I have 4.7 GHz nailed down, but I can't be sure yet. My system is weird. If I go too far (like 4.8), I can actually pass all stress tests for hours, but immediately after shutting down a stress test, a game, or shutting down Windows, I get a memory dump.

Also, I've noticed that if I push the CPU too far and lock up and/or get a memory dump, the system is not stable for several minutes at a reduced clock speed. So I have to be very careful about testing my pull-backs. For example, I tried to hit 4.8 again last night after 4.7 proved to be stable. It failed and then I went back to 4.7. Instant failure for several minutes after. Now it's fine. I've only seen that behavior in GPUs.
