Got a test cpu, mobo & ram to goof around with. When I get bored with it I'll throw in a Q9550 or similar and give it to the wife. :)

I can do a 3.2GHz run on my i7 when I get home. It is 10:33am CST now, I should be able to get it run by 5:30pm.
Poke349: I finally got a new waterblock, the Heatkiller 3.0 CU. I can't believe...
At 4.4GHz, 1.38v it was around 75-80c load. This is on an Apogee waterblock, custom hold down plate and a 370 GPH pump with a 30 pass radiator (copper tubing, aluminium fins). I really need a new...
I believe this is due to you having the older quad core. It does not have an integrated memory controller like the i7, yours is on the chipset rather than the processor. Also the i7 is triple channel...
Thanks :) Perhaps not at the longer runs, I'll have to test those later on.
It is sitting here in the original DFI box, I guess I'll sell it at some point. I really want to get some 4.5-4.6GHz...
Ditched the DFI X58 T3eH8 and got the EVGA Classified.
Here is 4.4GHz (shows 4.2 due to turbo), 3.6GHz Uncore and 1.65GHz memory on the x64/SSE3 binary:

Got a 3845B259 tonight from Microcenter, it needs 1.37v for 4.2GHz and needs 1.39v VTT for 4GHz uncore. :( The 3849B018 I have does it at 1.34v with 1.34v VTT for 4GHz uncore, but, it acts weird with...
Do you or anyone know of any other cases where the mobo was the cause of failure in the overclock of a D0 but not a C0? I'd really be leaning towards the mobo, but, the C0 I have runs like a champ on...
Something is seriously weird with that chip. I can't get high VTTs to work anymore, anything above 1.21 will blue screen. It takes a while at 1.23 to 1.26, 1.29 will BS within seconds. I lowered the...
I tried up to a 221 BCLK and it worked fine. I lowered the PCI-E speed from 103 to 101 and that cleared up a lot of the instability (worked fine @ 103 on the c0 however). I'm at 4.2GHz now with...
I too think I have a bunk D0. It is a 3849B018. On my old C0 I can get 4.2GHz stable in IBT/Prime95 24/7 and benchable up to 4.4GHz however the D0 even doing 4GHz stable is a complete no-go. I've...
That would be a surface mount capacitor. Does your friend still have it? I did that to an old GF2 MX way back in the day. I emailed the manufacturer and asked them what value of cap it was and they...
Do you know if the Gainestown turbo mode functions any differently than the standard i7? Also what are you using to verify you're dropping out of turbo mode with all cores running? The one I found...
In a previous post you mentioned you had turbo mode enabled, what is your real clock speed? For example the PI program says my i7 at 4.3 is 4.1GHz due to turbo mode. Also, what are your memory...
I tried the Intel compiler but the vectorization it performs is still quite inferior to hand coded asm almost all of the time. I gave up on using it for that so unfortunately any SIMD instruction set...
When you think think the new version will be released? I'm very eager to try it out on some older systems that have very little ram. I haven't disassembled it yet but I'm wondering if the non-sse3...

About a liter or so. I tried to get 4.4 but by the time I was done testing the ice was gone. :) I'm surprised at just how much heat that i7 can dump.
Good job on the memory optimizations, looks...

I did some runs at 4.1 (20x205) but I'm messing around now at 21x200 w/ turbo mode. As mentioned before it doesn't seem to detect that I'm running at 4.2GHz. I tried 21x205 for 4.3GHz but...
Wish I had saved all the results posted in this thread. :(
I'm curious again about a few things:
Do you think you'll maintain a result list?
In the Validation.txt output could you include the...
Good stuff guys, thanks. The Core 2 being able to issue single cycle SSE/SSE2 packed instructions really gives it a huge boost over the older K8 & P4 chips (should be 2x as fast clock for clock in...
