So I am now on my fourth Asus X99-A since March. System specs:
Intel 5820K, (2) GTX 980Ti SLI, 32GB Crucial Ballistix Sport 2400, Samsung 512GB 950 Pro m.2 NVMe, 4TB Seagate HD, 1000W EVGA G2 PSU, Phantes TC14PE 3 fans, Windows 10
1st Board: blew running Prime 95 at 4.5GHz / 1.325V taking CPU with it.
2nd Board: 1st PCI-e slot died randomly
3rd Board: Died running Intel burn test at 4.5GHz / 1.275V taking CPU with it
I was replying to a post on this forum about temps in Intel Burn Test. The user I was replying to had a similar setup to mine, so I thought I'd give IBT a quick run on my computer to confirm that his temps were normal. Big mistake!
4.5GHz (1.225V) - my 24/7 OC - instability detected after 51 sec (201W)
4.5GHz (1.250V) - instability detected after 51 sec (206W)
4.4GHz (1.250V) - ran fine for 10 minutes (203W)
4.5GHz (1.275V) - ran fine for 5 minutes then BSOD (214W)
(wattage reported by Asus AI Suite)
The system would not boot after that, returning Q-code B2 every time. No display.
Replaced the motherboard yesterday and the new board won't boot either, showing Q-code 95, no display VGA LED on. Today I will be replacing the processor, and I expect that to fix it.
My conclusion is that this is a fine motherboard, but that it is not designed for extreme overclocking! I would just plain not run a 5960X on this board, because even a modest overclock would be risky, so why bother with all those cores if I'm current-limited anyway? Whatever the case, 214 watts through the CPU socket was instant death!
I was thinking that I could protect the system by setting a temperature limit in the BIOS of 75 or 80 degrees.
My hottest CPU core never gets above 70C, even rendering on a hot day. But running IBT, it got to 87C, and running Prime Small FFT, it gets to 90C. I was thinking that this temp limit would also act as a current limit, because those temps jump up instantaneously when AVX/FMA code is exectuted. In this way I could dial in a nice high overclock, without risking my machine should I unwittingly run one of these "power virus" programs. Who knows what apps in the future will incorporate these extensions afterall?
Stupid me for thinking that Intel XTU and IBT were anything alike.
