i7 3820 - 4820 Overclock Club - Page 155

post #1541 of 6498
need some help from my fellow asus board owners. turned my rig on last night and noticed things were running a little slow, ran ibt/prime and noticed that my clock speeds had dropped from 4.5GHz to 3.9GHz. checked ai tweaker in the bios and it showed that my clock settings to be 4.4GHz. i'm using a BCLK of 105 and core is at 44, which should give me a clock speed of 4.6GHz. i checked all my other settings and nothing changed, except for my overall clock speed.

is there anything that i could be missing or something wrong with my board, OC or cpu to cause this?

Highest multi for i7 3820 is actually 43 not 44. Even tho in your Bios you can set it to 44 in reality it will work as 43.

It might have something to do with your turbo core i hope that helps.....thumb.gif

has anyone else used a thermaltake water2.0 extreme on a 3820 yet?

with the fans on the silent setting i get idle temps of ~30c and with IBT on high i get a load of ~62c, this is at 4.625ghz 1.3v

the cooler was a bit pricey, i could have gone with the cheapest 240mm xspc rasa kit for like $20 more including fans, but i'm happy with it so far

EDIT: the rasa rs240 + two scythe AP-15s comes to $42 more, and shipping costs on top of that

Not American here but isn't the thermaltake water2.0 extreme double the price of air coolers like the NH-D14 and Phanteks other there... What made you go with it?

Thats nice but radiator size is not the only determining factor there. Power of the pump and above all having a seperate reservoir makes a lot of difference, not to mention the ability for future expansion. In a similar scenario, a proper water loop will keep the temps way cooler compared to a closed loop having the same rad size and will give you a lot more overclocking headroom.
But it is all down to personal choice afterall. If you are happy with what you have, thats all that matters. thumb.gif

i just found a test comparing it to an XSPC kit, the one that has a thicker rad than the one i was considering:

http://hwt.dk/Test/38123/Thermaltake-Water-20-Extreme/Test-og-overclocking

difference wouldn't be so large i guess

@thecrim it's not quite double the price of the phanteks, about 40% more. tbh it was partially an impulse buy, i needed a cooler and didn't wait to wait for shipping, and my local store doesn't carry phanteks or noctua. i could have returned it, but i'm happy with the performance



GFlops varied probably because i was using the PC at the time of testing

Well, I would have definitely gone with the XSPC seeing the small price difference (XSPC waterblock alone is a great product)
To be honest, I have never seen a test that reflects the real life performance of any item. Most of them are biased, sided and marketing oriented. Also you never see these guys conduct the tests, numbers can easily be manipulated, changed, raised, lowered etc.whatever needs to be sold. In this case I suggest you watch this guy's videos regarding cooler performances.(this is just one of them, he tests and compares many coolers realtime);

Okay well I haven't seen too many of them around tbh. Would be nice to see a full run without you using it when you have the time.

What was the ambient temp for those max/idle results?

next time i'll go for a custom loop coolsmiley02.gif



ambient temp is about 70F, ~21C
