Long time lurker, first time poster. Finally got it stable! 4.5ghz HT on @ 1.36vcore
i7 920 D0 @ 1.36 vcore 4.5ghz - Cooled by Corsair H100 (is that considered water cooled?)
Asus P6T SE
12GB DDR3 Corsair Ram
1x Radeon 5790
1x Radeon 5870
Corsair AX1200
Yes - "closed loop" water cooling. ;) 4.5GHz at 1.368v is very nice, but it doesn't look like you're stable - GFlops vary too much from 52-56. If the system is stable you should be getting less than 0.5 GFlop fluctuation, which means you may still need more vcore or QPI... unless you were using your system whilst LinX was running. Were you? :D
On another note, my Rampage III Extreme arrived today so now it's time to really let my 990X loose. 4.8GHz with HT enabled on air? It's possible. :up:
I sent you messages regarding those parts on the hardforum and got no answer. what's the batch of the cpu and what's the kit model of your mushkin?
Will the list on page 1 be updated or is the "club" already closed?
It's been a while but we still haven't got any 3930K or 3960X to fulfil the 5GHz stress?
Yeah, I'm running at 4.9 on my 3930K, beacase the damn VRM overheats on the Sabortooth.
I popped an R4E trying and settled for 4.75GHz for the top drawer systems.
Gflops are way too low. Looks like its throttling to me. Try running tmonitor or realtemp turboGT while linx is running and see what the multi average comes out at. Should be 135gflops minimum at 5ghz with a 2500k.Quote:

First quick test with new I7-2600 5004MHz Batch L145A899 Motherboard P8Z68-V Pro. Cooling with water

I saw his a while back and thought it looked like a nice chip, and fortunately I now have one that is very similar.Quote:

You should get 5GHz with 6 threads, definitely... if not with HT. :yepp: Very interested to see how you get on with it. :up:
I didn't ask about the IMC, but all his bench's that I could find show him around 3700MHz. No idea the voltage though because he didn't use HWMonitor or AIDA.Quote:

Rules state at least 20 runs, and the pic has to be taken while the 21st run is in process.Quote:

Yes that is the correct version of Linx, however you need to update your intel math kernel library binaries.Quote:

Download the windows package.
Open the zip.
Open your LinX folder.
Overwrite all files in your LinX folder with the files that come in the linpack update.
I think I'm going to spend some time tweaking 4.5GHz because higher clocks are just too dang hot for this chip with air cooling, and tbh I'd be happier running it below 1.4v if possible, so 4.6GHz may be on the cards. I'm at a 2-3C disadvantage since going from the TRUE Cu to a regular TRUE, but it does take a fair bit of strain off the CPU socket.
I'm guessing your 990X will do 4.5GHz at about 1.35-1.375 like mine, but ofc it depends how hard you want to push it in LinX in terms of performance rather than stability.
What about those on SB-E with retarded amounts of RAM. Running a 64k problem size takes a very long time. Can we get in this running 16GB (seems to be the standard) for the tests?
Take out some ram for the test...Quote:

Max temp was 83C, so only 63C above ambient compared to 85C... Astounding! :D
136.5 x 33 for 4504MHz, uncore @ 3685MHz, mem @ 1910 8-9-8-24-110-2T, C-states enabled

Gutted that this run crapped out at such a late stage and with such consistent GFlops... oh well, nearly there. :yepp:
