Look at the tables and that doesnt seem so, the good ones are spread all over the place with plenty of below average ones filling the gaps, there doesnt seem to be a pattern at all.

I guess there are more duds being posted lately...
Mine passed linx, prime at 1.34 @ 4.8Ghz too. Needs 1.36v to be completely stable and game stable though.Quote:

10.20-10.30 are nice scores. Maybe 2600K is my next CPU :DQuote:

still cheaper than what most of us spend looking for E8600

Everything!!! I still find value running Prime and IBT but its strange to need more volts for games than stress testing software.Quote:

Depends on temps as well.
Kinda pointless to run prime if the temps get to 90C (and thus crashes and bombs), and black ops doesn't top 65C, and runs 8 hours stable...
But that's for gamers. People who use their system for other things may need prime 8 hours small fft stable.
I only use these cpu abuse programs for extremely short time periods now, just to make sure I can actaully launch something without corrupting the OS. (except Prime Blend, which is VERY useful for making sure the memory or IMC is working properly).
All my systems are 24/7 stable by 8hrs small fft then 8 hrs blend. I test them roughly by using Linx 25 passes with around 3-4gb of ram test out of 8gb.

lol i already gave up on this batches thingy.. the S/N low thing rubbish also
so far all the proc i tested does 5ghz between 1.5-1.52v

Guys, same here, I emailed ocuk to ask what batches they have but he cant tell me, no actual stock on hand I guess. A few guys over here ordered from ocuk when there was no stock here and one got a L040B307 (the same batch as 1day's). Has anyone bought from OCUK lately? Do they have C batches?
:)
i got one from ocuk and that was L040B307 and got one from local pc shop and that was l040b307 as well one needed very high core 1.65ish at 5373 and other same batch only needed 1.5 at 5387 both these went on 54 multi and roughly same max frequency and would not ebven boot at 5mhz higher even though could do all 3d tests pi etc at 5mhz lowerQuote:

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
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. :yepp:
+1.Quote:

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

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

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. ThanksQuote:

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.Quote:

liek said before a batch nr is just a guideline, but tells usually not much We had 5 CPU from the same batch, 2 did 5.4 benchstable, the worst 4.9 lol... so maybe you got a good one... you will only find out if you try it...
I'll do my best m8 :DQuote:

Edit: No, its not a special cpu , it doesnt like 53x so maybe with bclk I might bench at 5400, then I will test the 24/7 clocks.
Edit2: Ok it seems happy priming at 4800 with 1.400v , then 5000 with 1.45v but it looks like 52 is it. Batch is L051B142

please somebody try GTA IV EFLC more stressing than linX even IBT :D

Nice cpu, thats above average. I found a couple of 54X max cpus from a bunch of 53X top 2600Ks.Quote:

My current 2600K does boot with 56x but cant find hdd when it should start loading os, no matter what voltage.Quote:

Go back a couple pages on this thread for everyone's explanation.
Should run Furmark during LinX for total stability
wait a minute r3sy4, 9 minutes isnt enuf. u'll need to pass at least 20 runs to conclude stability.
Naturally.;)Quote:

Look at the difference in GFlops. Also, it pushes the chip to the absolute max. I past 20 passes in LinX ( with old libs) but needed more voltage to complete 5 runs in IBT (with new libs and AVX).

can booting at X51 but not stable at all.. damn !!! selling it then ordered new one :D hope for better batch

i have 2 intel ssd , put one with SP1 RTM (final) and the other no SP1
ok gflops on SP1 are much better yes, but the rest its same and not only that to be stable i need 4 notches of vcore and all tests runs the same or better some non SP1
i have 2 mates that tested and its the same
this is my opinion of course, rememeber SP1 has a new implementation on memory management
cheers !

its better to use LLC1 for OC, when you got it stable just enable CE1 and EIST states and you wont believe how cool temps you will haveQuote:

Won't get time to play with it for a day or so due to work (open case, take out vga, disconnect cables and fans, rip off heatsink, swap processors, reconnect all of the above, etc...)
The Batch should be decent hopefully - any comments on the serial number?
PolRoger has that batch and his is a cracker, can you get me one? Serious, I pay you and you post me one .... all chips here seem average to poor .... (oops I want a 2600K that clocks like that)
:shrug:
polroger - what did yours get to ? I didnt see any max multi tests, please fill us in.
:)
For a SB 2500K... that is a pretty strong batch although there can be both stronger and weaker in most batch(s). L041C124 might be even stronger? My chip will do 48X with ~1.280v load stressed maybe even a little less? Where did you source that chip? Serial number doesn't seem to mean too much for high multi 56x(+)... those seem pretty random.Quote:

You guys mind shooting me your default VID plus max multi, aka not your max stable speed.
I want to know max multi you can get passed the blinking cursor on asus and or the max multi you can post bios without 4E post code on giga if not using turbo.

This is my bench chip, seems very similar to rogers.
Maybe I need a tad more vcore than him because of the added stress with ram at 2133 versus 1600.
Thats about as much prime as i'm willing to toss at it.........L042B144
