Cleared 700Mhz on my X800XT-PE!!!

[Cornelious0_0]

Just thought I'd post this up.....cus it's a bit of a milestone for me, and I was gonna be looking for any suggestions people had regarding a few things.

First off, I had the computer sitting on a stool next to my front door, with the screen open...and a house fan blowing at the case. This kept the idle temp on the card down to about 16C.....and the load around 25C - 30C. Yes this is on watercooling.....but nothing extra, a plain ol' h2O.....so far.....with a 3.4E @ 4.3GHz right before it in the loop. ;)

At this point there are a few things I wanted to get your guys' opinions on after clearing this latest hurdle with my card.

The GPU's voltmod has been done up until this point via the Pencil mod. I am looking at soldering it on fairly soon, but am still not 100% comfortable with my (un)steady hands. I was wondering/hoping that there might be a working droop mod for this card by now, because this is kinda ridiculous to tell you the truth. I set the voltage to 1.85v, and under load (with or without the CPU overclocked) it dips down to about 1.76v in 3DMark2001's nature scene. Eventually my clocks are going to want more then 1.76v under stressfull conditions and I might not always be able to set the "idle voltage" high enough to compensate for the dip.

I need to know 1) if there's someone fairly skilled that I could send my card to to get voltmodded, and 2) if there IS a working droop mod or not.

Also, at this point I dont have the funds or creativity to setup a water chiller of any sorts...and I was purely thinking of getting a Pelt setup and running on the card now. Once the XT-PE is on it's own water loop what can you guys recommend for parts and a wattage of Pelt that I look at.....and/or what kind of idle/load temps I could be looking at hitting with a decent sized Pelt.

I know this is more of a question thread then a celebratory one.....but the Pelt setup and getting all 4 voltmods soldered onto my card is the next step or two for me.....and I just wanna get as much input as I can.

What do you think of my baby so far? I figured that 700Mhz aint bad for a straight h2O setup with the card running right after my Pres-hot in the loop.....can't wait to see what she'll do Pelt'd with some more powa. :D

impressive, i cant even get my 6800GT to overclock at all on the core :rolleyes: having said that, its still cpu limited even with my oc on the 3000+

Yeah, which is kinda sad......this Pressy is holding this thing back so much....I really wish I had the cash to pick up the Gigabyte s939 board and an FX-55 right about now. :(

[mikead_99]

That is a very nice clocking XT you have. I've had a small handful of them and haven't broken 700 MHz on any with volts and a pelt. I had one that did 680, un-mod'ed with pelt but the sucker died beofre I got to have any real fun with it. Thank god I hadn't mod'ed yet, and got it locally for a quick, painless replacement to the Gigabyte POS I have now.

OK, regarding droop, I think you will always get a little. I hoped the over-current mod would result in less droop, but didn't for me. Pelt recommendation, 172W with the DD block. It outperforms the Swifty block with 172W by quite a bit (10C or so loaded) in my loop. It is much more of a :banana::banana::banana::banana::banana: to condensation-proof then the Swifty though.

[gclg2000]

take to a local electronics shop. I think your rolling the dice though. If it burns itself out, you out alot of money, for once you solder on it. Bye bye warranty and bye bye nice card already and probally bye bye on getting another one like it. "I wish i had the money to do this and that." Hopefully you have the money to replace a toasted card. And i think you'd be better off getting a nice 90nm amd chip then chasing your [H] post with an intel. match the already awesome video card with a descent amd and i think you'll be better off. But the clock on your prescott is already pretty nice.

My $0.02, coming from a blown up 9800pro i eventually burned (with a nice clean POT mod) about 8 months ago.

516mhz on that R350 core btw :D :D :D

[Cornelious0_0]

Thx you guys.....yeah, I'm not planning now on attempting the mod myself.....as I'm not trusting enough in my own hands to get the job done. I'd much rather call around and get ahold of a shop, tell them what I need done, make sure they can GAURANTEE that they'll do a perfect job, and pay to get the job done...end of story. I'm fine adjusting the votlage after that point and troubleshooting things.....its just that initial soldering that I dont have enough skill with quite yet.

I'm actually looking forward to having the vGPU mod soldered onto the card in another way, because when teh CPU is sitting stock clocks with stock voltage, the gpu voltage will only dip so low under load, but then if I increase the cpu clock to 4.3GHz and up the voltage to 1.55v or so, the load drops farther.....and I'd like to have something as "simple" as a quick adjustment of a pot to compensate for that, rahter then not being able to erase and redo a pencil mod on the fly....which really isn't a viable solution.

I'm really excited to get the mod(s) done and get the card pelt'd....because as I've already heard, it's not everyday that you see XT-PE's hitting these kinds of clocks on plain h2O....and I wanna see what this baby's made of.

Thx to everyone for their input thus far.....sitting at my desk in my room at 1.825v the card idles at 30C, with a max load of 40C, what kind of temps do you expect I could see if I got my Vapo (taking the CPU off the same water) and added a 172W Pelt to the card?

Nice work :)

BTW, Good to see you around here.

[eva2000]

nice.. guess someone is forcing you to get moving on the ORB/ARC scores ;)

Thx bro, it's good to finally be "back in the game" again and a little more "active" in my oh so un-healthy hobby. ;)

nice.. guess someone is forcing you to get moving on the ORB/ARC scores

Yeah, well.....Centvalny just cleared 100k in AM3, James is close behind.....and they're both strong contenders at this point for our first 40k score back at [H].....but I'm still on top for 3DMark03 and 05 with 16,134 and 7,379 respectively....and I'm mainly looking to re-enforce those scores a tad.....and to finally break 30k in 3DMark2001....which I have yet to try at very much with these new clocks......they're all so much more picky about CPU and GPU clocks then AM3 (still my fav) is....so it takes a bit more time to get 'em right....which I'll be working on tomorrow. :cool:

[eva2000]

strange with your card clocks much higher and cpu speed close to mine i would of thought 30k in 3d2k1 was be easy considering I broke it last week

Powercolor X800XT PE stock cooling @609/603 - 3Dmark2001 = 30,004 (http://service.futuremark.com/compare?2k1=8342197) :D

That is actually quite interesting......or frustrating, depending on how you look at it. Is it possible that I'm just missing something here? My CPU will be maybe 20 or 30Mhz faster in this run tomorrow then it was for my 29.5k run.....the XT will be 27MHz faster, and I'll be running DX8 instead of 9.....but all in all I agree, there's NO reason why I shouldn't be ahead of you even with my old specs from that 29.5k run.

Mind suggesting whatever you can here......as now that I look at it, even thoug you're running EB memory and a 775 P4 (not a huge thing there) my XT-PE was clocked 66MHz faster then yours, and I was at a higher FSB and cpu clock.....yet I trail by almost 450 points?????

[eva2000]

450pts probably difference of low latency tRCD/tRP being 2. You running 2.5-4-3-5 timings probably doesn't help ? comparing Car and Lobby frame rates support that theory too

You checked to see if your cpu isn't trottling at those clocks ?

No throttling going on.....and at this point I really dont know.....I can see how your lobby and car scores woudl be that much ahead of mine, but I dont understand then how I'd be inching ahead of you in drag low but you'd be creaming me in drag high.
:confused:

We'll see, at the moment I'm ALmost convinced to pick up a 3000+ or 3200+ winnie and put my ridiculously nice overclocking luck to the test again.....cus if I can get somewhere between 2.8 and 3GHz out of one then I'll be MORE then hapy to have made the switch.....and selling my MAX3 and 3.4E would MORE then pay for the 3200+ and new mobo....so it wouldnt cost me a thing either.

Killer card you have there that could easily be a top benching card with the right mod's and cooling. Those are very good core voltages w/o the OCP mod being done.

Try running a high 5V line, that should fix the vdroops you are experiencing.

I have already turned my 5v up to the max with my OCZ PSU....about 5.4......and those are my results at 5.4v....before that it was even worse. If you could point me to any (fairly) simple PSU mods that could "up" my 5v I'd be much appreciative.....becuase the 5.4 DID help quite a bit...and I'd assume that higher would help me out even more.

I actually do have the OVP (OCP) mod done, and a 20k.....but I checked overclocks and votlages and whatnot before and after, including voltage droop....and I noticed no differences.

There are alot of threads about PSU modding right here. They might not be what you consider "easy" however, and do void warranty if you care about that.

I've never been one to take a LOT of worry in voiding warranties....I dunno if any peice of hardware I have in the house still TECHnically has it's warranty. ;)

I'll check around for mods.....but until then I'm REALLY eyeing up a nice 3200+ s939 setup with a Neo2 Platinum, that I could most likely get to 2.8 - 3GHz on my h2O....and after selling my MAX3 and 3.4E woudl only set me back $100 or less including the price of a new waterblock.....and I'd MUCH rather have a ~ 3GHz s939 setup to go along with my 700MHz+ XT-PE then this Prescott that's burnin' up my cards water, and is still struggling to keep pace with even 2.7GHz A64 already in most benchies. :(

[Boogotop]

nice X800XT clock you got here!!!

[Cornelious0_0]

nice X800XT clock you got here!!!

Thx, what's yours clocked at right now? I'm just trying to stack my rig up against some other right now.....cus I'll be picking up a Neo2 Plat and a 3200+ Winnie in the next week or so to throw on my h2O and go for 2.8Ghz. With the 3200+ at 2.8Ghz+ and some BH6 that I'm getting I'll be aiming for 91k for sure in my favorite, AM3, and at this point I'm trying to figure out what I might be sitting at in 3DMark2001 once I'm "done" with A64 Tweaker and have re-setup my 3DMark2001 partition with Win2k and DX8.

for me, on air, stock mobo, stock everything, and i really can't remember card clocks, about not to high though, max i've tested so far(new rig) is about 580 core and 570 mem, but i'm pretty sure that bench was run much lower, i'll check later on.

Either way, 3200+, gigabyte nf4, but most nf3 agp systems will be identical in speed/overclocking. 260mhz fsb 1:1, cas 2.5,3,3,7 running gig tccd. max the cpu will do on air cooling and only 1.75v. i think with watercooling, a better 3200+ and your card clocks you'll be way past 30k, not sure how much a 3.4E is, but if you go for a cheapish mobo like the gigabyte thats very very easy to mod then you'd probably not lose any cash.

I dunno though, seems to me even with that setup you should be quite a bit higher than you are.

i'd guess that with the neo 2 and a 2.8Ghz winnie and those cpu clocks you must be looking at being a couple thou ahead of me.

Yeah, I have come to the conlusion that I SHOULD be a lot higher then I am......but check the 3DMark link, that 29.5k score isnt with the sig clocks....but still. :confused:

I dunno, gonna just leave it be I figure.....and judging on some other scores I've seen with lower clocked cards and similarly clocked 3200+'s I figure that once I get DX8 up and running again on my 3DMark2001 partition (which half the ppl I've seen never use) and get it all up and running I shouldn't have a hard time hitting aroud 33k - 34k for sure....maybe higher, we'll see. ;)

BS:

Wheres your 3dmark 2k1 compare as your nature would be almost 340-350fps if you where at 700mhz ddr.. Your comapre shows a slow 640mhz ddr what gives?

Don't start threads like this without proof or screenshots "compares really needed"

:(

You're calling me on this.....wow.....I expected a bit of a warmer reception.

I've already told you, I haven't figured out what's up with my 3DMark2001, but my Aquamark3 in my sig is at 702Mhz. Please don't come back at me with something about how Aquamark3 is crap, because it's all that I've had time to run at those clocks.

If you don't wanna believe me then fine, I'm not asking everyone to believe me...but if you dont (for whatever reason) you could be a BIT more pleasent about it.

EDIT: I never even said that I'm at 700MHz on the ram, which you're reading as 640.....I'm "claiming" that my core has cleared 700MHz, which it has.....but the last time I ran 3DMark2001 was at 675. If someone can tell me WHY my 3DMark2001 is so low even at 675MHz and 4.29GHz I'd be greatfull, because I too thought it should be higher. I'll play around with it today.....and also try and get some 3DMark03 and 05 compares for you ppl who dont seem to believe me on this one.

I need to know 1) if there's someone fairly skilled that I could send my card to to get voltmodded, and 2) if there IS a working droop mod or not.


I now do five volt mods to the x800's....

I was supplying Vcore, Vcore Current Limit Setpoint, Memory Vdd and Memory Vddq when we
last talked. Since then I have developed a Vcore Droop mod as well to keep the cards active
droop circuit from turning into an active current limiter when the core loads up with Vcore over
about 1.580 volts at the desktop.
here is the link to vj's page: http://imageevent.com/gallery/viperjohn

[gocchin]

That's an amazing OC on that card... I also have a Sapphire and I've got it at 627/609 with the pencil mod at 1.48v (I'm timid to go higher ;) ) and it helped me score my 3DMark05 score. But at that speed I had to bring it down for 01 and 03 so I'm thinking of hardmodding as well. I did send an email to ViperJohn and I'm waiting to hear back :)

[Cornelious0_0]

Thx for the link joe, I had been in touch with him previously but I had lost the link to his page and couldn't remember the address.

I'll give him a shout again.

I also saw this guide from VR-Zone (http://www.vr-zone.com/?i=1579&s=1) is for a X800XT PCIe but might help you

Thx, but I've already actually got guides for all the voltmods.....just not up to it quite yet. In the next day or two I'm gonna maybe call around town to see if I can find some electronics repair shop that could gaurantee their work enough so that I could pay for them to do the soldering on my card for me. If that doesn't work out then I'll give VJ a shout.

Very nice core clock there my friend and Ill take the foot out of my mouth now. :)
