Asus Rampage V Extreme Owners thread - Page 166

post #1651 of 10621
Boards without OC socket will need more vccsa to compensate - eventually running out of margin.

No ill effects of 1.15v noted in my testing to date.

I tried 1.10V, but one time out of over half a dozen cold boot tests I locked on QCode B6. Tried several cold and warm boots with 1.15V and that seems to take care of it... so far.

When I was using a Gigabyte X99 Gaming G1, it would automatically set the VCCSA offset to +0.46V if I was running DDR4 2800 using the XMP profile. This is right over 1.25V total.

Hello

1.150 VCCSA should be ok. What are your primary memory timings at 3200 stable? Other boards have issues with ram speed of 2800 and greater so use a brute force approach with voltage to attempt those speeds.

This was with the XMP profile 2 timings of 16-18-18-39-2T. Ran LinX with 14GB allocated and 8 threads affinity locked for 9 hours no problem last night. Kicked off another test before leaving for work today. Memory still at 3200, but the timings lowered to 15-16-16-36-1T. I tried 4 or 5 cold boot starts before running the test and the PC started just fine with all 16GB of memory. Tonight, if this test is sucessful, I'm going to power the system off for a couple hours and attempt another cold boot. I'm hoping it doesn't lock on code B6.

Hello

If you end up at 3200/CAS 16 moving to 3000/CAS 15 will offer similar performance with likely lower VCCSA voltageneeded.
post #1655 of 10621
I'm not all that affraid of running VCCSA @ 1.15V. I'm not sure just how different VCCSA plays a role with the IMC using the Asus OC socket vs. the standard socket on the Gigabyte board I used before. I do know that my Gigabyte board applied over 1.25V VCCSA by default when using the DDR4 2800 XMP profile.

If that's a question you wont get a complete answer to as it would require giving away oc socket info.

Without OC socket, speeds over ddr4-2800 can be difficult. That's why the auto rules on those boards need to be so aggressive.

Hello

As I previously wrote without the OC Socket a brute force solution is needed to attempt to match ASUS memory speeds. That's about as much of an explanation that can be given.
post #1658 of 10621
Gotcha. I just figured if my Gigabyte board was so over aggressive with 1.25+V, then I shouldn't be all that worried with 1.15V with the Asus board.
