Slight Downclocking during Prime95

post #1 of 10
Thread Starter 
I'm brand new to overclocking, and i need a little advice. My i5 2500k is at 4.5ghz @1.32v, and for some reason downclocks between 41x-43x while running prime95. Is this normal? I have speedstep/turboboost disabled, just can't seem to find a reason why its dropping.

What are you temps? If it gets too hot, then it will downclock

This.^^ If your temps get too hot the board will automatically "throttle" down to potentially save it from damage. Your cpu temps can be in check but if the VRM's are getting too hot it will still throttle. Try placing a fan directly over your VRM's heatsinks to keep them cool. I actually placed a 90mm fan on the back side of my mother board tray blowing on the back side of my cpu and mossfets, has worked wonders on temps. My max temp for cpu was 55c at 4.2ghz and 1.4875v now its 51c.

the max it hit during prime95 was 62c, and idles around 32c, not too hot at all.

dont beleive so, the temp monitor i have placed on it never really shows it going above average at all. My air cooling set up is pretty good, case stays relatively cool. This downclocking start within seconds of running prime

readin some forums, it looks like i need to re-renable speedstep to be able to manually adjust short/long term power limits. Seems like they are intially 115/95 respectively, and need to be increased to stop it from downclocking... i'll have to try this when i get home. Still taking suggestions though incase this fails, lol

If it starts doing it right away then its probably not throttling. Must be some other setting.

yea ur right, seems a ton of ppl have run into a problem with downclocking due to restriction from short/long term power limits. Hope this is my problem too. Thanks for the help
