x850xt to x850xt PE?

m|Ke

I own a Sapphire x850xt pci-e and I was wondering if its easy to overclock it to a PE edition. Am I correct in saying the PE is exactly the same except 20hz on the clock speed, mine is 520 and the PE is 540?

Has anyone overclocked an x850xt before? I couldnt seem to find any info or reviews with overclocked x850 only x800 etc. Im new to overclocking, im just curious

Most X850XT's are capable of running at PE speeds, just make sure that you don't get any artifacting. Push it slowly upwards step by step....but i personally don't think that the Sapphire will have any problems reaching PE speeds.

hey thought i would chime in on this question..i do have a x850xt pe and i use the driverheaven 5.4 {for now} new 5.6 around the corner .. any way try and use the atitool.com devise it works great for setting up the card. also the clock settings for the x850xt have a near max setting of core-590.14/mem-624.86 at stock cooling temps,witch mine stays at 65-71 under load.i also in stalled a fan card under the x850xt and it seem to help [http://www.newegg.com/product/produc...2E16835888112] also i might add using aquamark3 has helped in those settings...

Almost all plain XT's hit PE speeds out of the box with software overclocking. ive even had XT's hit 570/600 on core and ram. as always with overclocking its the luck of the draw.

Is it worth it? Will I see any difference in gaming or just in benchmarks. I dont rly care about 3dmark score since i already get 5900+ so :/

generally no, however if you game at 1600x1200 with all the eye candy on, it can sometimes mean a boost from 25 to 30fps with a particularly demanding game bringing it from the shuddery zone into the playable range.

Right now you own the card so why not try it out, just overclock carefully and slowly, stress testing with 3dmark nature test on a 3-5 repeat to see if you get any artifacts, keep increasing at 10mhz and once you do just immediately back down.

Best way is to raise your core by 10mhz initially then test leaving the ram at default, when you start seeing artifacts, back down 5mhz until its fine. then do the same with the ram.

you wont damage the card if you overclock like this carefully, just make sure you dont run the card 24/7 at overclocked speeds beyond the limit of the core or ram.

Once you've discovered your acceptable overclock limits, then it's probably better to use RADLINKER to apply overclockng only where it does make a difference - no point overclocking the graphics while internet browsing!

I was able to hit the PE speeds pretty easily with Stock cooling.
The downside to it is that I run the fan at 100% when it OCs so it's noisy as heeeeeell.

so your saying overclock it just for when I play games, then put it back to stock when im not playing them?

daedal

Correct. You can set a "clock per application" by using Radlinker.
Basically, it allows you to select options associated to a shortcut. Say you want to use your OC when you play Half-Life 2, then you create a Radlink shortcut and in the options, set it to use the overclocked speeds. Other than that, leave your settings at default when in Windows/surfing.
