OEM / Retail, same card different box.Stereophile said:I'm ordering one of these cards today. Should I buy retail or oem ?
I want a good oc core of course ! Most of these are hitting xt speeds ? Would they be the same or will retail get slightly higher grade chips ? Anyone ?
FWIW I like the alien on the sappire retail better than the art on the oem.

Stereophile said:Ok thanks R1ck. Have an oem on the way.
Does aftermarket air cooling do much for oc these cards ?
what clock speeds did you get on your x1800xl?Bar81 said:Please. I'm running an X1800 XL OC'd and an OC'd X2 4400+ with 2GB of OC'd OCZ RAM on a 300W (fanless no less) PSU. You need quality not quantity.

Bona Fide said:You're running all this off a 300w fanless PSU? I find that hard to believe.

2 sticks DDR + X2 4400+ No OC and 7800GTX @ 490MHz (because there is no X1800XL) and a 7200RPM drive comes out to 260W on there. While you may have a quality PSU (IDK what PSU you have) according to your information and that website, you are probably within 300W anyway.
Bar81 said:The overclocking tool doesn't work properly (the scores in game don't change at all) so I'm just using CCC. The Zalman is set at 5V. At that I can get 550 core. I tried 575 but it locked up; haven't tried in between. Will play around more, but I'm running a quiet rig so max overclock isn't my biggest concern, quiet is. Still, runs under 60C on load in a very low airflow case. Memory is rated at 1400mhz so once an OCing tool is available it'll be OC'd that high, for right now it's at 1100 which is the max allowed in CCC.
Stereophile said:Ouch... I saw a lot of these on rage3d supposedly doing 600-650 on stock cooling.
Bar81 said:I really think the utility just isn't working properly. In my tests in F.E.A.R., which is heavily GPU limited, there was no difference in framerate between 500/500 and 550/675 at the settings I'm running 1280x768 High everything except no soft shadows 2x AAA and 8x HQ AF. That strikes me as very strange.
Besides, if all those boards were doing that speed then why did ATI have to issue another revision core, the 15 (all the XLs are 14), and slap on a dual slot cooler to be able to reach 625mhz and delay the launch to build up quantity.
ClearM4 said:Did you try the overclocking tool posted on the forums? Both nunyabiz and rickcain hit overclocks above 650mhz with voltage raised to xt level in ccc.

You should just test overclocks with 3dmark05 to see if score increases. If score increases then overclocks are working.Bar81 said:Yup, used the revised one from that link (2nd release) I'll play around with it a little more and see if I was doing something wrong.
ClearM4 said:You should just test overclocks with 3dmark05 to see if score increases. If score increases then overclocks are working.
I only suggested using it cuz you said something about the overclock untility was working and with 3dmarks you could check if there is an increase in performance. synthetic numbers are useless for gaming, but not for testing the same card at different settings.Bar81 said:I'd prefer to test with a real application. I don't care about synthetic numbers.

Bar81 said:Yup, used the revised one from that link (2nd release) I'll play around with it a little more and see if I was doing something wrong. Nope setting both 2d and 3d yields the same numbers.
LawGiver said:that oc utility is pretty much idiot proof so I doubt you are using it wrong. and it DOES work, my fillrate in 3dmark01 is near 10,000 MP/sec with my core at 628. With my core at 500 fill rate is around 7700, as one would expect it to be. your prolly just got a crappy core.
Bar81 said:Yeah, but that application in particular is known for shady reporting. I just don't trust it.
Alarmer said:Nothing shady about it, as mentioned before ok tool for checking out different settings and clocks. You have been reading too much Hard forums if you dont "trust" the application. Its not going to invade and violate your computer or anything
Bar81 said:Nah, I don't trust the results. I know it's not spyware or anything, just the results aren't reliable. Real apps are what I use and what I rely on in performance evaluations.
DASHlT said:Results are reliable, Specially when one overclock tells you the fillrate is 7000, and the next overclock tells you its 10k. Now that REAL application is telling you the overclock worked and its stable. Now it wont tell you a damn thing about perforamce on a game. But will tell you your overclock worked (and if its stable or not)
Could always run time demos..........
nemesis.ie said:I inititally had similar problems with the OC tool and thought that it didn't work.
I uninstalled the driver + CCC and installed the 5.10a based Omega drivers. Now it works perfectly, you can just pop in clock values, hit the button, the screen blanks for a few seconds and ..... your FPS go up.
I suspect Overdrive interferes with the settings on the fly (or when 3D apps are opened).
Try the above and do let us know how you get on ..... I've left mine burning in at 625/700 (8500 in 3DM05 with an A64 3000+ @ 2.7GHz) with stock voltage, water cooled with a TT rocket (only cooling the X1800XL).
How do you know its not working? You put a meter on the memory? I noticed that raising the mem voltage did not let me clock higher, is that what you mean?Bar81 said:Problems:
Memory voltage control does not work
.
ClearM4 said:PS. If your spending over $300 on a video card you really should have a water cooling setup.
