Throtlling, but can't figure out why..

post #1 of 6
Thread Starter 
So I have my t1090 BE at 4Ghz.

I can run OCCT and it doesnt cause a problem, but Prime95 does, and after I ran them both it happens in BF3 aswell.

The temps under load are quite low, idle at 35c on the chip, and 24c on the cores, under load in OCCT after 10-15 mins they reach 57c on the chip and 46c on the cores.

Can a cpu throttle from needing more vcore? I have it at 1.45v but with LLC on extreme (30%) it peeks at 1.536v.

As I was writing this post, it throttled again, and the temps are 33c cpu and 23c core. What's causing it?

It's been fine for a couple weeks, I tested it with prime and occt while running Heaven on a loop

I was just going to bump the vcore a couple and see if it fixes it, but idk why its started happening, so I wanted to ask here first wink.gif

Okay so I just left the system idle with the browser and a few sensor programs running, and it throttled again to 24.8mhz per core. the cores are at 21C so its definitely not heat. What else can cause a cpu to throttle? Memory? I reduced my timings a few days ago, but they've been testing fine with memtests and no games have been crashing.. Might just up the vcore a bit. I wanted to get as close as I could to 4.2 ghz on this chip, whats the max vcore for air? I have one of the best air coolers you can get though, which performs better than a bunch of closed systems (like the h80 in my other rig).

I know the Tjmax is 62c for the 1090T's but does that apply to the CPU sensor or the cores? As theres like a 10-15 degree difference at times

That is probably the power saving features on, they can go funny with AMD CPU's when using P95 and OCCT, try disabling ALL of them and retrying it

Hah! Funnily enough I didnt even think about that, I double checked the plan and turns out that Passive mode was on for my CPU on Balanced.

Changed to High Performance and tweaked a few things, lets see how it goes..

I thought when a cpu is controlled with the build in power stuff, it maintained your FSB and just reduced the multiplier? The lowest it throttled too was 8mhz per core. I mean I didnt even notice a performance drop because its such a quick drop, but its still a drop nontheless lol.

Ill run occt and prime again (I run them both at the same time) and see if it throttles now smile.gif

Also in the BIOS< is anything power related enabled there too?

Yeah I make sure all that stuff is off before hand, it seems that was the problem man, been running for 12 mins on both and no throttling. cores at 48, chip at 58.

I have a question maybe you'll know the answer. I have just increased my FSB to 205 (I increased it two at a time) when I got to 206 it was stable, but it took along time on the "Welcome" screen on windows login, even though it seemed to test fine in prime for about 5 mins, I restarted went back to bios and changed the FSB to 205 and the welcome screen instantly goes, and the overall feel of the system seems to be alot faster.

What do you think could cause that? Memory perhaps?

Yes the memory, same applied to me, also the CPU NB might want a small bump in voltage too
