VRM on the new AM4 motherboards - Page 115

post #1141 of 2001
Alright I just came back to ask how long I should run it after noticing its still only at 47c after 10 minutes of running Small FFTs. Saves me hours I guess xD.

My Gigabyte K7 hits about 65c running the latest version of P95 blend test. Board performs just fine but it's nice for folks like chew to post great informative vids.


I'm fairly sure my vrms are not that good. I'd assumed that the temp readings I have in hwinfo are vrms.

What are you running small fets for? Temp check? It doesn't make the heat that blend custom with 90% ram allocated. That will rise and fall as you go between differing work loads. I haven't seen temps rise much in that after an hour .

Not to mention is more real world as in bang load then ehh some load but stress hell out of ram.

Toss some well know 3d app on top of it and you got yourself a real stability test. Heaven , dirt2,3 can be used to..its pretty brutal.

Anyway i am armed to the teeth with betas now...lets see if we can get a tune out of this trombone by the weekend....this one is going to require quite a few tricks to get an optimized cpu oc if and thats a big if atm...one of these betas have some secret sauce in them for 32g...

The good news is....i have confirmed 120 ref clock to be stable on it. Guess some overlooked some stuff...thought 107 was the limit wink.gif

I wish my vrms stayed below 70C frown.gif

That's the reading I get from the VRM's on my board after running P95 blend for 30 minutes. Haven't tried other stress test. What temps are you getting when running P95 blend?

Very nice. I really should push my RAM some more but I'm more of a set it and forget it guy these days. Glad to see you're pushing these boards hard.

So because I like the K7 so much I tried to put a 120mm fan directly on the VRM zone (case open, the fan isn't attached to anything as I have no way to do it)

After 20 minutes of prime 2.91 custom test max vrm mos temp is 66C, but was generally staying between 60 to 65. Still not great temperatures if you ask me, but they're better than before.



The fan used is the one labeled as "system pump fan 5" at 1200rpm

It's pretty clear my major problem is the poor airflow vrm area is getting, despite the heatsink Gigabyte provided is absolute garbage, so I ordered this little thing hoping it helps cool it down https://www.amazon.co.uk/gp/product/B005JSA4K4

What's the point if temps stay below 80c? Do you stress the hell out of ur rig at all times?

Huh didn't know they still sold the spot cool, interesting results on the VRM, I'll be curious to see how the spotcool does compared to your direct fan approach right now.
