as far as i know tRAS should be tRAS = tCL + tRCD + tRP (+/- 1)
and tRC should be min. tRC = tRAS + tRP

could that explain why there is such a high Vcore in the pic as he thinks its the cpu that is unstable when its most likely the ram?
indeed..

if hes so skilled, why does he have such messed up ram timings? was that part of the messing around?

you ever watched one of the phenom overclocking videos? chip was probably staring in it but those timings are kinda krazy. maybe he was going to be overclocking in windows and had it all set up or something god knows

i believe he was trying to find which of his boxed chips would accept high voltages before going to bench with ln2, saves him time and money

*YAWN* this prime95 game is really boring 30 mins so far
Yes, but it wasnt the rams fault. Its the something to do with the imc. The memory works fine at 1600 7-7-7-24 in another system. AMD does officially support speeds over 1333mhz and this is because their memory controllers. There are many phenom 2s that work fine at 1600. Even mine does at 8-8-8, but any tighter and i start getting errors. Also i must run 2T when 1600mhz. But on the other hand i can run 1500mhz @ 6-6-6-18 1T all day long, with the same ram. We all know and evn AMD knows their memory controllers are one of the next big focus points on their upcoming cpus. These are just an extension of the same old ddr2 controllers they have been using for years. There will be much better memory controllers coming out with future amd cpus, these current ones do not take advantage of ddr3 much at all. I just cant wait to see a new amd architecture. This phenom 2 was really a big jump in the right direction. Just think about all the things they go right this time. They really went skimpy on the cache to keep cost down. When they realease some models with more l3 and perhaps a better imc. See no on is really paying attention, or noticing the fact that the q9550 and q9650, which amd has matched in performance, are running twice as much cache as the phenom 2s. This is a big deal when working with quads. The phenom 2 is very powerful to be able to compete running half the cache of intel counterparts. But you see this is where amd makes up for the cost of the bigger die

he is so skilled, i've been following his posts at xs for a while now and i have learned a ton of information from him.

the ram timings weren't messed up, it was pulled down to its tightest timings because he was testing and at the same time benching on air

yeah i noticed the same problem with 1600mhz and the command rate. i haven't read up much on it an jumped in the deep end just figured what was going wrong before i read this post lol. im just keeping 2t with the cycle time loose and its sound as a pound. i can either have stressed out nb and ht or stresst ram timmings. cant do both at the same time its not having 1 bar of it. ill figure it out next week when i have the time.

im really tempted to sell this chip and try out a 900e or a low wattage 955 that ive spotted. im keeping an eye on these funny oem chips they seem quite promising

I have set Vcore 1.368 in bios,when i stress cpu and i am watching the voltages with cpuid hw monitor the maximum vcore is 1.41 and the minimum is 1.36.

Can some1 give me details about this cause?
