So, wtf are you talking about?
(Do the math, thats a 22% OC on the memory, and is 48C under full load! I haven't even tried pushing it either, and barely have even touched the core!)

I reinstalled OS when I installed this card, so cleaning old drivers and stuff is out of the question. Biggest problem I had was with Bioshock, I would get vpu recovers every 5-10 minutes. It would pause for 30-45 seconds then resume the game. Farcry 2 crashed a bunch of times when I ran the action scene in the benchmark tool. Mirror's edge crawled sometimes which I found was my mistake, I had set Physx to On. CoD WaW crashed a few times with vpu recover or would freeze during multiplayer causing me to abandon that game for now.
No need to explain yourself, if you're used to Nvidia parts being overclocker friendly its totally understandable that you'd be disappointed with an AMD card.

Good gawd man how can you handle the noise at 65%. :Q

Here was the last Nvidia OC thread I replied to. Where is that monster Nvidia OC again? And before you compare 4870 overclocking to GTX260 overclocking, be fair and compare a 4850 since both of those GPU's (the 4850 and GTX260) are just lower clocked/less enabled parts of their big brothers.

THERE'S the Nvida fanboy post, lol These are hilarious. Yeah you should at lease post exactly what the issues are, your fan settings, cooling setup, etc. 4870 here on 64 bit OS, and never had 1 single issue at all period. The ATI drivers have been great to date and I also am one of the few who use and really like the CCC control center.

Yep it certainly depends on a particular GPU but like I said, Nvidia parts typically achieve higher overclock in both % and % performance gained from that overclock. As for your comparisons, a 40% overclock on the 2900pro shouldn't be surprising given that 2900pro is just a market binned 2900xt with a reference clock of 740MHz, a 23% overclock of its own.Originally posted by: SlowSpyder
1 - I don't know about that... I would say it depends on the perticular GPU more so then being red or green. I've had two cards that were supposed to be very good overclockers. My 7900GS even with a Zalman wouldn't go over 550MHz from the factory 450MHz. On the other hand my 2900Pro, I pushed it to 840MHz and it didn't miss a beat, from the stock 600MHz. I'd say that 40% more on the core is pretty decent for a GPU, wouldn't you?
And if you compare those 9800GTX+ clocks to what they were originally, a G92 GTS or GTX at 650 or 675MHz you'll see that its ~16% OC, not to mention the 9800GTX+ reportedly hit ~850MHz from additional overclocking.2 - The fastest 4850 I've seen is overclocked to 700MHz on the core. I'm not up to date on all of the 9800GTX+ cards, but the fastest factory overclock I see at Newegg is 785MHz (XFX). That's about 12% for the 4850 over reference, and 6% on the 9800GTX+.
Yep and not only is the GTX 260 achieving a higher % overclock, its going to benefit more from each MHz increase as there's more transistors benefitting from the OC.For a 4870 it's 815Mhz (Asus) or about 8.5%. For the GTX260 216 the fastest I saw was a 666MHz GTX260 (XFX). That's a healthy ~15.5% overclock.
Sure, but Nvidia parts have been historically better, which was my point all along.I see that depending on the card any can have a pretty good overclock.
Sure you can, you just look at the stock/reference coolers. Nvidia uses their dual-slot blowers on all of their high-end and even most of their mid-range parts, which has been this way for years. ATI uses a similar design that simply doesn't perform as well in practice on their high-end parts, and a flimsy single-slot cooler on their mid-range and low-end. Non-reference are a different story obviously as they take much longer to come to market, typically cost a premium over reference, and often have negatives of their own.3 - I don't know that you can really prove/disprove that since they are different coolers cooling different GPU's. I guess you can say this is true if you consider the slow fan speed of the 48x0 cards, but that can be addressed in CCC or 3rd party software. I can handle launching CCC, checking a box, moving a slider then hitting OK personally.
Yep, but do they cover overclocking on AMD parts? I don't know, I'm asking, as I'm sure many are interested.4 - Doesn't XFX carry over the same double lifetime warranty for AMD cards?
Of course more good options is better, because if one software program doesn't support a new driver, you'll have more options until it does. Fortunately for Nvidia users they don't have to worry about support as both RT and Precision are written by Unwinder, who typically has fixes for Nvidia parts within a few days of a new driver release.5 - So because you say updates for Rivatuner come later then Nvidia cards that somehow makes it any less valid as an overclocking/tweaking tool? Also, I'm not sure how 'more' 3rd party overclcoking tools is even a feather in Nvidia's cap? I don't want 8 different programs, I want one good one. I can overclock my 4870 with Rivatuner or ATI Tool (but am actually just using CCC right now). Those are proven, good programs. ATI Tool says, "No limits overclocking." as well. I don't care if Nvidia cards have 800 different overclocking tools, I'll take one good one that works for my card.

The 8800GT cooler was fine at 29%, I didn't have any troubles with mine at stock or overclocked. It wasn't as good as the dual-slot coolers but it certainly didn't spawn a widespread movement to replace it with after-market coolers either.Originally posted by: thilan29
The 8800GT sold extremely well and came with a very crappy single slot cooler for a while then they changed I think so it hasn't "been this way for years".
Which just proves my point it doesn't perform as well as Nvidia's reference blower. TDP on the 4870 is the same as the GTX 260 and actually more than the 55nm GT200s, so I'm quite sure anyone with a mid or high end NV card could achieve similar temps with NV's superior cooler, provided they were willing to go deaf in the process.Actually the 4870 cooler is very effective but is loud. Read videogames101's post...he hits 48C at load on an OCed 4870...try to achieve that with any mid or high end nV card.
I was actually hoping for something definitive from XFX about it, perhaps someone who bought an XFX product who was interested enough to research/ask XFX about it.I'm fairly certain they do. It states here that they are "modder friendly"

No, I'm comparing the stock G92 GTS and GTX speeds of 650 and 675 to the overclocked G92 9800GTX speeds at 770MHz or 14% OC. The 55nm version allowed for additional headroom and a higher reference clock for the 9800GTX+, but fewer OC factory parts.Originally posted by: SlowSpyder
Chizow, are you comparing the default clock speeds 55nm GPU in the 9800GTX+ to the 65nm version of the GPU in the 9800 cards and calling that an overclock? It was a shrink which generally will result in a higher clock speed or power savings at the same clock speed, or a comprimise of both power and speed. You can't call that an "overclock." The 55nm chip clock speed is 738MHz, the fastest factory overclocked card I see is 785MHz. I don't see Nvidia's supposed overclock superiority here.
That's certainly your opinion but history does not support your claims.I still do not believe that Nvidia is superior to AMD in anyway when it comes to overclocking. I do believe that both companies have particular GPU's and model cards that are known to generally overclock very well.
Its really simple, if you have a small gear and need to turn it at a higher RPM to begin with, then compare it to a big gear that performs similarly at lower RPM, which do you think is going to gain more from more RPM?I also can't say that I buy it that you get more out of a GTX260 overclock since there are more transistors. From my limited testing my scores scaled well with clock speed. If I have time I'd like to do run some benches and put up the numbers if you want.
A 9800GTX cooler is certainly worth the extra price though, as you don't see people rushing to replace their Nvidia stock coolers with aftermarket coolers that totally defeat the purpose of a low-cost part to begin with. Why spend $50 on aftermarket cooler if you can spend that $50 on better hardware that comes with better stock cooling. Similarly now that 4870 512MB is $180 after MIR. Would it make any sense at all to buy a 4850 for $130 and then pay for after market cooling when you can get similar cooling and better hardware for the same price?You're right that the 9800GTX/GTX+ cooler is better then the 4850... but then again the card is more expensive. But, as pointed out, Nvidia has used some pretty shabby coolers too. I still have my 7900GS cooler laying around with it's mighty 40mm fan. I remember lots of temp problems with the 8800GT's when they came out as well... smallish single slot cooler with the fan stuck at 12% or something like that. What I'm getting at here is that I don't see some kind of clear cut superiority by Nvidia in this regard.

I've owed cards from both companies. And to be honest never had a problem with either of them. I just went with what gave me the best bang for my buck. And this time its Ati, 4870 to be exact. As far as drivers go, Nvidia and Ati are both good, never had any problems. Its all luck of the draw
