7850 Upgrade.

I bought a new cooler. Freezer arctic pro revision 2. Got it off a local free ads site for £8. Brand new, unwanted gift. I'll fit that and see what happens. I have hears 2 different methods of putting heat sink paste on. The guy that I got the cooler off suggested I put a small grain of rice size bit on the centre of the cpu and the tightening of the unit will spread it out. A well known high street shop has recommended wrapping cling film on your finger and liberally covering both the heat sink bottom and cpu with silver paste.

Any suggestions which is better?

Thanks for everyone's input so far. I have temps of 50 degrees or slightly more in gameplay and convert x to dvd 48 degrees ish but handbrake went up to the mid 70's before I stopped converting - on the standard cooler.
 
I wouldn't recommend putting it straight on the cooler (unless its pre-applied) as (for one of my rebuilds) I trusted my firend to put my H50 on (while I answered the phone), he covered (use a whole tube) the contact face in paste (couldn't see any copper) and applied it.

Temps were pretty poor, around 40C idle.

When I had a clean out I reapplied the paste (after spending what felt like 3 months cleaning the old paste off) and saw temps drop to around 33-35C idle. :)

My method is a 'blob', bigger than a pea, just. corner to corner, but only half way in the middle (if you see what I mean). Though it can be a pea too, both do the same job, being spread by the weight/contact of the cooler. :)
 
Edit> Beat me to it ^^^^ :)

As the guy you got it from said; one or two rice sized applications in the center of the CPU is the right way to do it, the base of the Cooler will spread it evenly across the CPU's heat spreader as it tightens.

If you spread it yourself you will end up using far to much to get what appears an even spread, it will just spill out the sides and end up too thick.

For temperatures you don't want it running much past 65c for lengthy times.

AMD rate them at 62c, thats a little conservative, 65c is not going to hurt it, anything more than that is the limit, you did right to stop Handbreak at 70c, that is too high.

I'm on hand to help you with it should you want it, just let me know :)

Stock his CPU runs at 200Mhz HT-Bus x18 (3600Mhz) he currently has it set to 210Mhz x19 to give him 4Ghz, His RAM multiplier is set to (what looks like 9x) to give him 1890Mhz, slight fluctuations in the HT-Bus speed may actually be putting out 212/3Mhz to give him his cited 1933Mhz.

I didn't suggest setting HTL to 266, just the memory speed, i.e. HTL * divider.

1933 is weird, close to what you'd get from a 7:8 divider at 210...?

Best thing would be a new thread in the OC subforum to help find the best settings. Easiest one (without knowing the dividers he's got access to) is probably putting it back to stock HTL and divider (3:4) to get the best out of the memory, and cranking the multi up to 20-24.

With respect you're confusing the whole thing.
Actually, you know what, go ahead. write down instructions for him to mess about with HTL dividers and clock rates, that i have to see. when your done giving all of us a migraine i will show him where the Cmos reset is so he can get his PC to boot again.. :p
 
Thanks Humbug. There are a lot of options on the board and I don't really want to mess with any of them. However; doing what you stated has had impressive results. Thanks. Is the Pro 7 rev 2 cooler from Arctic any good?

Yeah, you could go on all day messing on with it, but its pointless as it all ends in pretty much the same result, nice and simple where it just works. thats all anyone needs really, if you want something fancy you probably already know how to delve deeper.

As for the cooler. Its an inexpensive cooler, thats not saying its cheapo, its not a bad cooler, its quiet, it will give you a reasonable overclock. :)
 
Well. On an unmentionable auction site I just bagged 3 items. A H80 cooler from Corsair for £14 used which I have collected locally and 2 motherboards that will come in the post. I did not want the 2, I won one and could not cancel the bid on the other so I've 2 intel boards.

1x 1150 Asus H81M Plus board £15.50 delivered and an Asrock 1155 Z77 Pro 3 for £40.

Oh well, now I have a few choices :(
 
you wanna scout around for either a 2600k,2700k or 3770k cpu

I have my msi tf3 7850 with a 2600k and its great

I think the h81 supports k chip overclocking (unofficially)
 
Yes cheers Wazza300 I thought about the 2500k, I know of a cheap 2500s but they are not as good. Not to sound ungrateful but the H80 cools to 59 degrees under prime 95 at 4.4 gig so YAY! but it's so loud...no really really loud. :(
 
im using a noctua d14 on mine with 2 akasa apache fans

its utterly silent think mine doesn't go above 72c @ 4.5ghz,fans only spin at 1100 or 1200rpm

the thing with the 2500k is it lacks hyperthreading which is handy in bf4 and crysis
 
On the lowest speed setting it's actually ok, perhaps I was a little hasty in my judgement..

72c - isn't that really hot. My motherboard sticks a big warning up if my cpu hits 65c?
Is it different for Intel cpus?

I'm a touch confused - the H81 doesn't support any of the processors you mentioned as it's 1150 and they're 1155? His other board is 1155 though (Z77)

Personally given you've spent nearly half your budget I would probably just go with a 2500k or 3570k in the 1155 board and sell on the H81, even though I don't like Asrock as much as Asus.
 
I was told that Asrock were Asus's budget section? maybe got that wrong. I know of a 2500s chip for £70 but it's an S not a K. Maybe good, maybe bad choice for a gaming chip.
 
*redacted*

I'd try to get a 2500 or 2500k, the S is a fair bit slower when using multiple cores. Ideally the K as they overclock so very well, but still can be expensive even now (I've heard people say they can find 3570k's for less just due to the hype about the 2500k! Not tried buying either so don't know if it's true...)

Edit: Removed the Asrock comment, see wazzas answer below.
