Venice CPU's not clocking High on the HTT?

[Kunaak]

I been hearing rumours that Venice CPU's just don't OC well on the HTT speed, meaning ram speeds aren't gonna be as easy to hit 300+ at 1:1 with TCCD and such.
it's not the ram, but Venice CPU's just not clocking as high on the Memory, as thier older counterparts, the winchester and clawhammer and such.

is this true??

if so, does anyone have any examples of this, or examples of venice CPU's clocking nice and high on thier ram??

no problem hitting 318. Though neither my brother's Venice nor my SD can hit over 330htt, not sure if it's memory controller or bios problem, my TCCD was doing up to 345 with Winchester :D :D

Ran some super-pi 1,8 32m and Prime95 with a 3800+ Venice @ 310Mhz here. Seems like its stable.

310Mhz 2.5-4-3-6 2.9v - XMS4400C25

Make me 3.... 300+ on my 3200+. Trying to get the damn mem to keep more 3's! 2.5-3-3 at 300 instead of needing 2.5-4-3 to scale more would be nice. Have to tweak away on this timings bonanza board/bios.

These puppies are going to mature and be the real deal. I been longing to get back to Newcastles after my luck with Winnies. Finally topped my luck on 130nm with 2.7+ on air. Just praying for no cold bug.

Well I was able to get 300mhz with my winchester and now I had to lower to 267-270mhz for my Venice to pass prime. These things are always going to happen, there isn't a set standard for success or failure for that matter since everyone out there is running different hardware in their systems, so the answer will always elude us. But yeah i had to lower to 267, go figure.

Heh, ain't nothing gonna be worse than my winchester with my TCCD. Won't go over 215mhz at any timings. Hell it won't even boot at most timings. This is in 2 different boards as well, and the memory has been tested in other rigs much higher than 215...Come to me my Venice :)

Venice has a better ondie controller than winny. Youll occasionally find the dud Venice but mine does 315 1:1 and maybe higher with different ram and mobo. The winny wouldnt even do 300

Hi Kunaak :)

I've heard this damn thing too.

A friend of mine can't pass 335 with his Venice 3200+ no matter what CPU multi, so he can't go over 335*10=3350MHz @ DIce and this is really bad.

He tried 510-3 bios and nothing was changed, so now he try 510-2, I hope that he can solve a lil or that the new stepping of Venice went a lil bit good (coz I think that is AMD 'problem', not the mobo)...

All test is made with 2*512MB UTT so not 1:1, but no matter what RAM divider.

My SD can do 310 stable but haven't tried anymore than that. My Winchester on the other hand could do 350 stable.

Im not sure if this is relevant but i will post my findings. I seem to have reached a limit on HTT but it varies according to wht divider im running

:confused:

For example running 322HTT with a 9:10(183mhz)divider is the max i can post with stabilty.

Running a 5:6(166mhz)dividier my stable HTT speed drops to 292!

Once in windows I can run higher HTT speeds, i.e. 330HTT with a 5:6 divider is no problem, can run SuperPi 32M at 3ghz.

Does anyone know if their is a limit on the divider in relation to HTT speeds? Ive tried the newer bios's but my results are the same.

The memory on each occasion is well within the clock range it is capable of. Researching this problem right now, hopefully someone can provide some input. Maybe this is the same problem other peeps are having

I have no problem running my San Diego at 348 x8 with 510-3 Bios :D :D

[bmaffin13]

mine seems to crap out at about 320ish HTT with low multi and divider

I have no problem running my San Diego at 348 x8 with 510-3 Bios :D :D

I see your not using a divider, if u have time I would appreciate if u could try this out for me.

323x9 using a divider of 9:10(183mhz). See if you start getting instabilities after this HTT. Your brd HTT goes passed this, your mem definately hangs at this speed, not sure abt your CPU though. I would very much appreciate if you could do this for me

thanxs

hey Ben805, cant u do me this favour?
