Broken APEX49 Posted June 18, 2021 Share Posted June 18, 2021 Hello Which item is the cache voltage adjustment? It seems impossible if 46 or more is auto Quote Link to comment Share on other sites More sharing options...
Hyperhorn Posted June 18, 2021 Share Posted June 18, 2021 Cache voltage = core voltage 46 is pretty much the limit for Rocket Lake on ambient and voltage doesn't really make a difference (at least for me). 1 Quote Link to comment Share on other sites More sharing options...
Broken APEX49 Posted June 18, 2021 Share Posted June 18, 2021 The specific way to actually raise the cache is Do you mean to raise the CPU voltage? Quote Link to comment Share on other sites More sharing options...

Cache voltage and cpu voltage are the same. Some cpu can do 50/48 on ambient and some can do just 50/46. There's cpu that need to raise voltage to much for more then cache 46 on air/water but like Allen said, with some cold it's very easy. 1 Quote Link to comment Share on other sites More sharing options...

I've had to use 1.600v IOM to get 32m pass 3866+ in Gear 1 using 1T But I can usually pass 32gb Dual Rank 3866 1T Gear 1 at 1.350v IOM 1.4000v SA. Also SA sometimes needed to be up to 1.7v 2 x 8gb Single Rank dimms are really hit or miss on Gear 1, they either work or do not work. Gear 2 5000+c15 etc seems to be where they shine I don't recommend these settings but I've used them a few times on ambient and so far no problems Keep in mind, you will fail a Lot !

Broken APEX49 Posted August 13, 2021 Share Posted August 13, 2021 I'm currently challenging a 32GB dual rank, but I'm struggling to even boot at 3600mhz! I can't adjust the third timing. It's hard. Quote Link to comment Share on other sites More sharing options...

I can't adjust the third timing. It's hard. On ASRock OCF or APEX XIII ? If it's OCF make sure to enable XMP in bios And if the dual rank kit is 2 x 16gb B-Die every kit and cpu I've tried can POST 3866 with 1.410v SA and 1.360v IO Memory or less For the Special (not so) Secret Sauce try playing with ODT resistances. Try ODT WR (A1) 120 ODT WR (B1) 120 ODT NOM (A1) 34 ODT NOM (B1) 34 ODT PARK (A1) 48 ODT PARK (B1) 48 You say you have problems with the third timings well look at this image I posted above and copy it. Try leaving tWRRD_sg and tWRRD_dg on AUTO to start as they are tied to other timings such as WTR_L, WTR_S, WR, CWL maybe Frequency, CAS Latency (CL) and Command Rate (CR) Could even try to leave things like WTR_L and WTR_S on AUTO and maybe even WR because bios does not show tWRPRE or tCCD and WR = WRPRE - ( CWL + CCD ) . CCD is usually 4 btw Example WRPRE 28 - ( CWL 9 + CCD 4 ) 28 - 13 = 15 so in this case tWR is 15 Last thing is some memory dividers just won't boot or are way harder. So just try a lower or higher divider with BCLK to get desired frequency EDIT: Just want to clarify things a step further To clear things up a bit . . . On some boards, tWR in the UEFI does nothing and instead needs to be controlled through tWRPRE (ASUS). Dropping tWRPRE by 1 will drop tWR by 1, following the rule tWR = tWRPRE - tCWL - 4 On Intel, tWTR_S/_L should be left on auto at first and controlled with tWRRD_dg/_sg respectively. Dropping tWRRD_dg by 1 will drop tWTR_S by 1 and Dropping tWRRD_sg by 1 will drop tWTR_L by 1. Changing tCWL will affect tWRRD_dg/sg and thus tWTR_S/L. If you lower tCWL by 1 you need to lower tWRRD_dg/sg by 1 to keep the same tWTR values. This (lowering tCWL) might also affect tWR as mentioned above. Further Simplified using the Food Chain template haha! CWL If you lower this by 1 WRRD_sg/dg these lower by 1 WTR_L/S and that makes these lower by 1 WR which raises this 1 by relation of the rule tWR = tWRPRE - tCWL - 4 Edited August 16, 2021 by GtiJason 3 Quote Link to comment Share on other sites More sharing options...

No need to touch regular IO voltage. Dual rank needs a healthy dose of SA and IO M depending on your cpu and what bench you're running.

Broken APEX49 Posted August 22, 2021 Share Posted August 22, 2021 The OS is booting. But the pi stops after about 3 loops. io mem is 1.65v I've increased SA to about 1.68v. 1 Quote Link to comment Share on other sites More sharing options...
