Memory that has been Modified

[MaddMutt]

I have 3 different sets of High-End memory that I was able to purchase from our site

1) Corsair Dominator Platinum 2x4GB DDR3-2133 8-10-10-27 - It also shows a secondary timing under Asus SPD Info of DDR3-2132 7-8-8-24
2) G.Skill Trident X 2x4GB DDR3-2400 9-11-11-31 - It also shows a secondary timing under Asus SPD INFO of DDR3-2399 8-9-9-27
3) G.Skill Trident X 2x4GB DDR3-2600 10-12-12-31 - It also shows a secondary timing under Asus SPD INFO of DDR3-2599 9-10-10-27

Who did these mods and at what voltage do I run them??
The standard 1.65v is not enough and the board posts with memory errors.

Thank You

Slightly off-topic: What is a modified memory?

I think you're looking at XMP2 settings.

XMP can hold more than one profile. For starters, process should be same as normal, just select the XMP profile. As with any high performance ram, compatibility isn't 100% guaranteed so you might have to manually back off clock and/or timings.

I think I only have one kit with two XMP profiles, Corsair Vengeance LPX 2800 with profiles at 2800 and 3000, so the extra speed was a nice extra I wasn't expecting. I heard that ultra-fast DDR4 kits might have a 2nd lower profile for systems that can't make it to the faster one.

If I'm right then:
1. Micron IC maxed out by corsair and can't run any tighter or at much higher clock
2. Samsung IC which at least on ambient temps and reasonable voltages wouldn't run so tight
3. The same as above

Looks like you are reading info from SPD/XMP table in BIOS which can be wrong like most CPU-Z tables or someone programmed profiles for harder benching (what I actually doubt). These timings can be also values for lower clock profiles as they fit to 1600/1866/2133 profiles of lower clocked kits from these series.

Test Corsair manually at 1.65V but don't expect too much above XMP. Test G.Skill at 2400 9-10-10 1.65-1.70V or 2600 10-12-12 1.65-1.70V. Max will be something like 9-10-10/9-11-11 at ~2600 or up to 2800 10-12-12 up to 1.8V+.
