My cpu hit wall beyond 320 HTT

[sobol]

Hello
To be stable with 1T setting i must use 8x multiplier,

Useing 10x260 mhz with 2T aint problem, To get equal with 1T i would need 8x325 mhz but at 320( thats max stable with prime95) im hitting wall, my htt is 3x. Im sure its not problem with my memory coz:
- memtest is working at 325,
- prime95 fails at any of 3 torture tests after max 5 mins,
- my ram is doing 240 2-2-2 stable , and it tested.

What i tried for now was:
- 1.7v for chipset - no go,
- changeing htt to 2.5x - no go,
- rising lil vcore - no go

Any ideas what else i can try ?

Max HTT for you CPU most likely.
NewCastle?

Heh seems its not my max htt, Jonspd from ocforums told me to relax mem timings, was ridiciolus for me but it worked...

Relaxing timings gived me some stability. Setting:
Trp: 3
Trcd: 3
Tras: 8
Give me 30 mins of prime95 stability at 325 mhz and 236 mhz mem ( before playing with timings failed after 2 mins )

Strange coz the cpu can operate on this memory at lower htt,
example 245 mhz 2-2-2-6 without any problem. You have any idea why is that ?
And what you think about rising vdimm? This friday im doing psu voltmod and ill set 3.5 v for it, im wondering if that will alow me operate on 240 mhz 2-2-2 with high htt ?

Tight timings put more stress on the memorycontroller.
That's why you got higher with losse timings.
