May 7, 20179 yr I gave these Corsair's Dom GT 2000c8 v7.1 psc kits which successfully passes 2600 8-12-8 spi 1m and 2570 8-12-8 32m at 1.82v on FX 8350 and ASUS 970 Aura. With the g3258 and MVII even the 2400 with 8-12-8 gives 00 and reboot loops . I have tried +0.1-0.3v sa and for io 0.1-0.3 (both digital and analog). I enabled additional DRAM Training option too. VTTDR is set half of dram voltage (1.7-1.85) . I disabled MRC fast boot option too. Is this epicly bad imc or board (the CPU is a x6 vn batch)😢
May 7, 20179 yr Author I have tried booting into 2400 divider with auto RTLs but it doesn't post and reboot loops with last code 00
May 7, 20179 yr Some G3258 has garbage IMCs, but should still be able to do 2666C8. Try 0.45/0.25/0.3 for SA/IOA/ID. It depends on what seconday and tertiary timings you are using though.
May 7, 20179 yr Author I loosened all secondary timings and tertiary timings and also tWCL to 8 as I heard some PSC have issues in lower tWCL. What about the DRAM REF Voltage t and also the slope settings? I have not tweaked them yet but I think 2400 c8 should be possible without slope adjustments and other fine tuning
May 7, 20179 yr That's too high, I meant +0.45v, so that would be 1.3v or 1.25v. But it is more likely to be the timings and ram, but check if your board it setting offsets or actual volts. At +0.5 (or 1.35v) or higher you are likely to start risking your hardware and probably getting negative scaling. Should be: 8 12 8 28 1T 12 88 4 4 4 6 10360 4 4 5 4 15 4 4 4 4 4 11 11 11. For 2600 or 2666. Will most likely need 1.9 to 1.96v. But some PSC stops scaling around that point too, so if it refuses to boot at high volts then back ot down one step at a time. You might also need to manually set the RTLs/IOls to 4/4/40/41. Edited May 7, 20179 yr by Noxinite
May 7, 20179 yr Author Yeah I did +0.45v on sa that would result to 1.45v.defualt is 1v..For ioa +0.3 and id +0.25 Edited May 7, 20179 yr by ACD
May 8, 20179 yr Author my board shows default SA as 1v . I checked it out.some guides and the default is .85v SA Edited May 8, 20179 yr by ACD
May 8, 20179 yr Author 2200 works...2400 doesn't .I tried 40/41 RTL too..Btw it.I think 2400 c8 should be easily possible ? Edited May 8, 20179 yr by ACD
May 9, 20179 yr Author so, i updated to a different bios. I tried 2400 with 8-13-8-28-2T , 5 108 10 4 26 5 5 8 RTL when on 2200 was 40/41 so I set the RTLs to 40/41 manually and IOls to 4. It still gets overclocking failed and reboot loops i once got 3E debug code..
May 9, 20179 yr Could be too loose IOLs, try dropping them by one at a time, like to 39/40. Corsair didn't make particularary good PSC though... Edit: Try these timings. https://imgur.com/uOUeS8C Edited May 9, 20179 yr by Noxinite
May 9, 20179 yr Author It is probably a case of potato imc or board I have tried several settings including 125 strap and lower mem multi still I get oc failed when above 2200. I have adjusted the tWCL to 7 , disabled fast boot and others...I have tried coolice's bios.am I doing something very wrong ? Edited May 9, 20179 yr by ACD Typo
