  • I have seen a lot D9PFJ taht did 2400 8-8-8 with 1.92,could manage 32M with 2V+,pretty competitive if you freeze them

nah, I threw out that trident kit, I had a feeling that is was a poor clocker bbse ( only 1 of 3 was capable above 2400mhz with loose timings ) so I bought a good PSC kit from a friend of mine.

slew rate 2 , bios F5o , primaries set manually, 2nd - 3rd are auto, vdimm 1.75v

now testing cas 7 and then full spi 32m runs.

if you cant set twcl to 7 then CAS7 performance is bugged

 

as i see there is no such an option to change twcl manually in this bios.

cl8 is the way for this kit, c7 is not working high enough. or im just a lame.

Dude if you can do 2600 8-11-8 32M stable on air, then you bought yourself a very good PSC kit. My BBSE only can/could do that. My PSC Flare kit can do 2600C8-12-8 at 1.88Vdimm...

well, then there is an option to change that :D thanks for the help !

 

2600 8-11-8 will be a though run ..

1.83v is surely not enough, haven't tested more vdimm yet. Don't want to kill them on the first day. Will test it tomorrow :D

anyway 2200 7 11 7 and 2600 8 12 8 is doable neither 2400 c7 nor 2600 trcd 11 .. :/

UD5H / F15q

 

Gskill F3-18400CL8D-4GBPIS (XMP seems to work with tWCL 7 ,tested with x22/x24 and x26 C8-12-8 feels better then the last beta)

 

P.S. can someone please try Patriot Viper II Sector 5 2400MHz 9-11-9-27 (PVV34G2400C9K)

didn't have much time (threw in the towel) ..can't post XMP@1200... tWCL 7 or 8 lol,no problem on the other MB running 4 banks with the same settings as 4Gb here

I thought i did have decent samples, but they clock pretty average.

PSC and samsungs are fine on my UP5 I think. Neither run well at their default settings in XMP, but I cant ask for much more when I pump the vDIMM.

Hy boys...I have bought today a Z77X-UD4H mboard but I have problems to set memory PSC as the older MAXIMUS GENE V. Befoure I set 2.600 MHZ CAS 9-12-10-28 1T @ 1.65V. What the subtimings settings ? With Asus I have the profiles.

 

Thanks

Nothing boys...I have issues with TRANSCEND PSC ram...I can run with XPM PROFILE and in Windows rebooting with 2200 divisor...Automatically the mboard set 9-12-12-34 1T and I can put bclk to 106 mhz with result of 2.368 mhz...

Hey guys

Any bios recommendation here for the z77 g1 sniper 3 and mem OC with various ICs?

 

 

Edit: G1 Sniper 3 Bios F7. Transcend Axeram 2400+ ( 4GB PC3-19200U CL10-12-11-28 (DDR3-2400) (TX2400KLU-4GK) ) not working. Even a no go with loading XMP Profile, BCLK auto etc.

I tested the kit on another brand motherboard, no problem for 2800+...
