i5-2500K/2600K batch number and o/c results

[andressergio]

mine arrived

#L045B021

very cool and nice chip needs to enable internal pll on x48

its summer here 26C ambient no AC im ma room





cheers all

Batch # L044B441. S/N 35042116A1807

This chip is totally different from my first chip. The only way to get it semi stable @ 5G was to relax the ram timings to 9-9-9-28, took a lot of tweaking in bios as well. Runs about 8 degrees hotter than my first chip with same voltages. Max boot is 53X 32 M stable.

hi

my first go

[andressergio]

Congrats to all nice chips i have to try 5ghz

guys for those using SP1 of W7 my friend OC Nub, The Real 7 noticed that its harder to get stable on SP1 need more vcore notches...like 4...i took it out and its totally right

anyone is using SP1 ? i was a big fan of it it also give more GFlops but its true in pay off less stabilty

cheers all
Sergio

SP1 has AVX enabled, so it uses all your CPU has to offer. Hence higher stress levels.

+1.

I love seeing 120GFlops in IBT though. Makes it harder to get stable, but its 110% stable once you make 10 passes.

Is there a way to disable AVX? Will it affect gaming performance in any way having it enabled in SP1?

[zalbard]

Using older Linpack library that doesn't utilise AVX is one of the ways.
But you can't really disable it entirely, no.
And it would only affect games if they supported AVX, and none do right now.

I think you have to manually download it anyways. There isn't a version with the latest linpack library that you can download. I did install the new ones into my IBT.

I guess I was more concerned with something in the background of the OS using it, just because it's enabled doesn't mean it's constantly in use right?

Right. Same as extra CPU cores, for example. They don't hurt if they aren't used.

Batch: L040B698

No screenshot for these:
4.7 GHz - 1.352v load - 20 min. prime stable then a crash
4.7 GHz - 1.360v load - more than 4 hours prime stable

But here's one:
4.9 GHz - 1.432 load - more than a few min. prime stable. The voltage isn't tuned, so it may go lower.

[dnottis]

L047B217 2500K from Newegg. Load temps are mid 60s, water cooled.

Without all the background apps running I get just over 70 GFlops in LinX.

[Asmola]

L046B509

[mean6]

Turning it up a bit batch# L045A951....seem's to need 1.4 under load for a stable 5ghz.

I have almost the exact same system. Cpu batch too. Any chance you could post your bios settings. I am having trouble getting stable at 4.8. It will fail at 18/20 on Linx. Thanks

Depends what you use the system for. 3 hours LinX/ATX stable results in a bluescreen within 1/2 hour to 45 minutes of rendering with 3ds Max unless I bump up VCORE. Same holds for some encoding.

[Dumo]

Aging ss still going...with L042B243

[aussie-revhead]

Which of these would you buy?

L047A898

L051B142

L041B739

A guy on i4 bought an L041B739 and his does 55x .... I bet if I buy one it wont , but its worth a try...

[Asmola]

L046B509

This chip does this too:

This chip does this too:

Nice Asmola , 5.2GHz low voltage

[aussie-revhead]

Does anyone here have an L046B102?

My 2500k L041B800 S#1984 max multi 53

Damn they sent me an L051B142, should I open it and give it a whirl or return it for another batch?

[EniGmA1987]

All batches are hit and miss. Some have amazing clockers, and then in the same batch some that cant hardly do 4.5GHz without a lot of volts. Same for all batches so far.

[GeorgeVasil]

L050A864 - Custom WC - Gigabyte UD4 - Prime 26.5

~4400 Stock Vcore 1h Prime Small FFTs
~4500 1.246v 1h Prime Small FFTs
~4600 1.272v 1h Prime Small FFTs
~5000 1.35v Bench-able (not Prime stable)

I didn't tried higher multiplier. Still Playing.

Very true indeed but I could find no good results at all for this batch, in fact the only reference I found to L051 here was that people were selling them after testing them. No 1155 list I found had any L051 results, GeorgeVasil above is the first nice newer batch cpu I have seen. George, please test a nice high multi and put my mind to rest.
