rombo Posted September 8, 2017 Share Posted September 8, 2017 Hi Guys, This is my 2nd attempt at OCing a rig. My 1st one was a 3930k and I tried overclocking it to 4.1Ghz and it is solid, never skipped a beat. my second rig is a 1950x that goes like this: CPU: 1950x Threadripper with coolant spread as per Gamer Nexus advised pattern COOLER: NZXT Kraken x62 MOBO: x399 Gigabyte AORUS RAM: 4x16Gb (64Gb) Corsair Vengeance 3200C16R PSU: Corsair CS850M 850w VIDEOCARD: GeForce GTX 670 (yes, laugh! ) I tried everything, can't even OC the RAM to the XMP level by flicking the RAM XMP switch in the BIOS. 1st sign of mucking around with the RAM Speed and I am stuck in reboot loops ad infinitum. I got the CPU running from 3.4 to 4.0 fairly stable, just upped the vcore to 1.25V and left all else automatic, just changing the clock multiplier. It's just a pity I can't up the memory a little more, as it seems that the Zen Family are mem bandwidth hogs in order to get high scores in benchmarks. Do you guys know of a guide to go about at experimenting a little more with this setup? I am a bit lost, as I can't find a forum talking about this setup with clarity. My Cinebench is below 2800cb and Corona Benchmark 1.3 sits at a depressing 5.6 Million Rays/s I see guys having well above 3000cb and 6.5Million rays in Corona benchmark 1.3 so I suppose I must be doing something wrong...

Administrators websmile Posted September 15, 2017 Administrators Share Posted September 15, 2017 Might be needed to ugrade the bIOS, first BIOS editions at Ryzen also had memory problems. The point is that especially new amd systems have bigger problems to oc dual sided memory sticks as far as I know Quote Link to comment Share on other sites More sharing options...
