Woah there, you may want to rethink that:

"The big one though is the one most non-workstation users don’t know about: non-uniform memory access (NUMA). In a 2P system, there is a communication link between the two processors, running through the QPI at 8.0 gigatransfers/sec. Unless the software you use knows how to deal with that, then memory required by a thread for one core could be on the DRAM on the other processor, which makes memory accesses (and thread stalls) very, very long. This is why when some users build a 2P system and they only see a slight speed up (or a speed decrease), rather than a 2x increase, they wonder why performance is not what they expected"

It appears that it will work. I put my W3690 in the P6T SE, BIOS 803...and the BIOS says max multiplier is 63. I set the multiplier to 27, BCLK 133, Vcore 1.35 to test. Settings stayed.

very well. so even on motherboards P6T the w3680-90 are unlocked. thanks for testing

I wouldn't be so sure of that. It's mainly the X58 revision that will dictate if the unlocked multi will work or not. The early X58 boards I would imagine don't have the updated X58 revision

Well I was just doing it for Ferro10's benifit. Not sure if I want to keep it this way. Low end board (it doesn't even support SLI, just X-fire) and probably has 4-phase CPU power instead of the 8 or 12 phase the R3E has. I'd have to figure out what GPU I want to use in this rig. Orginally had a HD7950, then got a R9 390, but its slightly too big...its a Strix model..I can sort of get it in here. Just put a 560 TI in here because its easy..short card. I am actually working on a 2P rig too, but for BOINCing... gaming on a 2P would be ... interesting... the last 2P I had was a old Dell PowerEdge with 2 P3-933s and 1GB of ECC DDR. Don't remember if I tried to game on it, but I used to game on a 2P P3-533. Built it because I thought it was cool...lol

how to determine the revision of x58 chips ??
post #7168 of 7956
Realize I've used Multi CPU system before. My last one is a D5400XS, I understand but I have quite a few applications that can utilize such, also i hear DX12 likes it too?

Thats the famed SkullTrail, is it not? How was it?
post #7170 of 7956
How was it? It's still going, I haven't disassembled it yet.

Running Twin X5670's at 4Ghz, 4x4GB of Kingston FB-DDR2 Ram, with fun 4-4-4-12 Timmings(Very fast for DDR2), Has currently Twin Micron M500 120GB SSD's in RAID 0 for the OS, and 4x2TB Seagate Constelation storage Drives, has a Soundblaster Audigy 2 zs Platinum Soundacard, a PCI-E USB 3.0 Host card, and a Quadro K5000 strapped in. Usually only use it for rendering models and video and stuff. The goodies, it also has an IBM T221 As the monitor(with the twin Matrox boxes) so i have it at 55Hz at max res smile.gif

Tbh, I've tried gaming on it, was meh, but playable for sure. Nothing insane, Just wanted a sperate workstation i could do my renders on and have my main rig open to game smile.gif

Also one in the Office and one in the "Cave" hahahahahahahaha


Sorry for the thread jacking, but i think the photo's are justified






Kana-Maru probably remembers tongue.gif

The photo's are BEFORE i swapped the GPU's out, I haven't taken recent photo's of it because life kicked me from the server x.x
