tomottow, i left my note at home

Jus enter you're primaries and leave the rest on auto and write down what Memset 3.3 says in Windows and make changes in Bios

[Primoz78]

Thx for the answers will try @home

G.S. Technician any news on the settings?...I can prime (small FFTs) 16h+ but in super_pi, blend prime and other appz reboot in a few seconds...

Gotta tell ya man you don't give any info at what clocks you are at number 1 and from that vie we could guess indefinitely as what you may or may not be running

[Primoz78]

OK here we go...I have tried:

4-4-4-12 2T all the rest on auto @ 800mhz 2.0-2.270V
4-4-4-12 2T all the rest on auto @ 835mhz 2.0-2.270V
5-5-5-15 2T all the rest on auto @ 1066mhz 2.170-2.310V
5-5-5-15 2T all the rest on auto @ 9xxmhz 2.170-2.310V

and so on...but nothing helped to get super_pi or prime95 blend stable...it crashes in 1-10 seconds...

Have also tried with memset and put the values in BIOS but still unstable...

try 5-5-5-18 trfc 42 all others on auto, i know it is loose but we'll get it stable first then tighten them up.

Ok it passed Super_pi 32mb without a problem...but @ 835mhz...will try to push it a bit higher...

Good to hear, try a 5/6 divider which should put ram @ 988 with same bus speed,or 4/5 which is 1030

Already done...successfully



Now will try to tighter the latencies...

Hmmm I think it is at the limit of the stability cause it works only once now at the same settings is not stable any more...strange...really strange...

on the bios we recommend the following

All Precharge to Activate = 6
TRFC = 42
TWR = 14
TWTR = 11
TRRD = 3
TRDWR = 8
TRTD = 3
All precharge to Refresh delay = 6
Precharge to Precharge Delay = 2
TWRWR = 5
TWRRD = 5
TRDRD =5


those setting is not something tight, but that is the correct setting

Thx...will try but I`m loosing my mind with the config What about the voltages? 2.3 for max @ 500+?

if you need 2.3 i would suggest dropping back to a 1:1 divider and tweaking the latencies so you can run @ 2.0- 2.1v try 4-4-4-15 trfc 36 with 1:1 ratio and 2.0v if it's unstable try 2.1v and keep a good fan on any ram you overclock. doesn't need to be hi speed just good airflow.

[Primoz78]

Will try but I have no luck with low latencies...I have a 140mm fan over the NB/PWM area and it also covers the RAM slots so no worry for temperatures

[Primoz78]

G.S. Technician have tried the settings you suggested but no help...another week of testing stability and if not stable I`m going on other 2 sticks of RAM...

ive tried everything and this ram doesnt even want to run prime stable 1/1 divider over 800mhz , and no one seems to know why the only person ive seen do is this guy rgm or something like that but he didnt show his settings ill have to send him a email
