I plan to get one of those for a machine at work (together with an 6400+ maybe).Originally Posted by jpierce555
About vcore modding. According to this article, the next step is to identify the resistances connected to pin #4 (FB) and pin #33 (NB_FB) and shade those.
The chip is located next to the mobo's power plug, close to the cpu. Guess I must remove the heat spread connector to inspect this pins.
You mean the cpu cooler? Not sure what you mean by heat spread connector.I plan to get one of those for a machine at work (together with an 6400+ maybe).

Just be careful and try a 2hb pencil first. I have a 2hb and a 6hb, used the 6 on my g-card. I would rather you be the experimenter LOL.
Sorry, yep I mean the adapter for the cpu cooler.
I think I identiefied the nb resistance but for the cpu I'd need a camera. Used a normal pencil and shaded the nb resistance. AMD Power Monitor did not show a difference but I think that tool reports the vid's. So I try prime95 with lower nb voltages now to see if it worked.
EDIT: It did not work. Must wait till room mate comes home with a camera.

Well I emailed Asus engineering again this weekend since they never replied last time. This time I asked them flat out if they expected the voltage issue to be fixed.
This is really frustrating.
Did you notice disabling the TLB fix via AOD does not bring the same performance increase as disabling it via the Crystal CPU?
Found this in the specs. I think I shaded Rf,nb and not Rfb,nb.
Hope that pic will help identifying the right resistances once I have a few pictures.
I plan to mail em the bu list for 601 once I checked a few things I found with 501.
Makes me look into vmodding, so i don't mind atm.
I noticed a difference between yellow and red mode but aod's red mode.
To apply the fix with crystal cpu one must modify the two msr registers on all cores, otherwise only the first core will use the tlb. That might have an impact on benchmarks.
Hey ya'll I have the thread over on Legit, was wondering if any of you have ran water cooling on the NB? I just spent the week fabricating an external water cooling box and the cpu is water cooled (x2 6400 heat pump), the zalman NB water block is laying up on the PSU waiting and ready (after heavy mods to the now not so universal WB lol).
So far it's been a really good board with the X2, but had to wait on NB water cooling for a solution to the NB water block rocking on that tiny chip. Neoprene rubber hand cut is what I'm planning unless you have a better idea.
Flipped 450 FPS on a volt modded 8800gt under Lightsmark on the board. The only better I've seen is an 8800 gtx max oced under water and it crunched a 555 fps.
Lemme know if you watered the NB (safe/not safe) and if you used a gasket and if you did what material.
Much Appreciated!
BTW nice thread/forum
Hi Methious,
Linked your thread on the first post, glad you joined.
Can't help with nb mounting but I'd be interested in a good solution. I googled for nb waterblock mounting on the M2A-VM. This mobo uses the same nb cooling but did not find anything usefull.
I remeber somewhere in this forum was a recommendation about nb cooling on the m2a-vm, just have to find it.
I got the 6400+, don't know if I'd go that direction again. It's the hottest chip I've ever run, even under water, Swiftech MCP350 pump, Dell XPS 710 Rad, Swiftech Water Block, runs 30C idle, 40-42C load. Under a ThermalRight 120 Ultra, load ran 46C with upward creep, nMedia PC IceTank ran 55C load with a lot of creep. Runs like a dream though if you don't mind lack of OC overhead (probably not going there at work) Normal non-100% working load it runs pretty good.

Dont worry about temps that much. Whatever it gets with stock cooler at stock volts must be acceptable or AMD wouldnt sell it like that. They would lose too much money on RMAs (do they sell those retail with a warranty? AFAIK oem has 0 warranty now)I got the 6400+, don't know if I'd go that direction again.

The 6400+ Black edition doesn't come with a cooler, I got the retail version and ran it with the nMedia PC Icetank at first, that's a 92mm 4 heat pipe and under load wasn't sufficient, ThermalTake Volcano wouldn't touch it, ThermalRight 120 Ultra did a good job if you want a cooler the size of a child's shoe box in there that weighs upwards of 2 LBS. Zalman 9700 does a good job.
With coolers of that magnitude the only ones suitable for full load it becomes an issue. It's a 95nm design, more nm means more electrical resistance, more resistance means more heat. Take a look at the AMD site and recommended coolers for the 6400, then do a search for them, after an hour I gave up and got the ThermalRight.
