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

[Dumo]

dumo u tested till what multi they boot with no internall PLL ? and 5ghz stable ? on them HT ?

i ask you this because its for a friend willing to do 5gh stable HT with it as my batch does

cheers and thanks
Sergio

I didn't test it on air. With SS initial boot up @ 53X/PLL enabled/LLC10/1.54Vcore bios/4cores/HT off.

Most of times if it stuck @ 4E after F10 then good chance that cpu max is <52X or <5300Mhz

Bought yesterday a dud, L042B243 2600K, thought it would do decent coz, was it Dumo? who got it to 58x? Mine wouldnt go past 5ghz, and it needed 1.52v to be vantage stable.

Now I have a new one, L108B066, but I don't believe in good batches anymore.

Same here, Dumo found a 58x awhile back so I went and bought one, boy, was I unlucky! It wasn't even stable at 5Ghz either, even up to 1.550v. That's why I gave up now, not binning CPU anymore.

[Demo]

with 4.8Ghz at +0.050 voltage offset Im getting like 70-75-78-71c with a D14, I've remounted this several times already.. such a huge temperature range.. wish they would all normalize to 71-71-71-71

i stick with my batch does x53 easy and needs a bit more vcore to x54 and im stable on 5GHz at 1,428 load

thanks dumo

Demo most of use have the same im on water and my cores are different its been like this since ages

just scored a 3102C197 best of two worlds costa rica c batch chip. Will report later on OC

Cant wait to see 60X

I had a lot of Costa Rica but they're all bad.
4.8Ghz with my C124.

[Demo]

Odd, both my 2600K's wont even do 4.5Ghz unless the VccIO is set to 1.100v is this a bios issue or a mobo issue? Im using F4 bios.

Probably found a better one right now



Tested for max clocks @1.6v and I reached that. I don't know if it can reach higher anymore

L108B066

What happens when the VCCIO is set to auto or 1.050v? 1.1v is only 0.05v higher...what happens?

I get errors on Prime95 SmallFTT test, almost instantly.

[Falkentyne]

But this does NOT happen at 4.4 ghz? (and it does not happen on Prime blend @ 4.5 ghz?)

Something's wrong...VCCIO is supposed to affect memory, and small FFT tests the CPU and cache...

I havent tested it at 4.4Ghz, actually I when I got my mobo UD4-B3 i went with F4 bios right away. 2 chips wont budge at 4.5Ghz unless VTT is 1.1 A friend of mine with the same setup went with F3B and has 4.7Ghz on all auto. So I tried F3B and left everything in all auto and just removed the power saving thing. So far its been running smallFTT for the last 15mins fine.

? high vcore +low PLL v ore low vcore an high PLL v ?

to x55/x57

[Ace.]

you dont ned more then 1,8V PLL for all Multis

[Demo]

Good?
Bad?
Too Much?
Way too little?

i usually spread even with a card Demo and goes ok

[andressergio]

depends on the chip Ace...some like low, some 1.8 and some above

you got pm :o

I would prefer a full spread on the IHS. I think that with no goop around the edges you are missing some opportunity to transfer heat to the heatsink.

ACE,

I have the same board and chip. I would like a list of your bios settings. I was able to do twenty rounds of LinX at 5.0Ghz at about 1.40vcore but cant get it stable any higher even with much more vcore and after that my cooling cannot handle any more it seems

[Demo]

This blows, 4.5Ghz with 1.360VID and - 0.025v offset gave me a BSOD after like 9hrs in Prime95 Blend with 124 error code.. What could be wrong? Is there a faster way to check for this.. waiting like 9hrs and it BSOD's after is just pure bummer!

@little_scrapper

So I manually spread it around instead of using pressure to spread it ?


EDIT:

I tried to manually volt it at 1.360 w/o any offsets this time

Ran 30 loops of LinX ( I dont really like this as ppl say it degrades the processor so fast )

Right now at stock 1.050VTT
Memory at 1333Mhz 9-9-9 1.5v
HT-OFF, all power savings off

All other voltages in AUTO, PLL over voltage OFF



On the first page 123 says VTT/QPI so I should be playing with the VccIO right and not the Vcore?


I would need some help in OCing my 2600K, should I continue to post here or just make a new thread?
