As was said in your other thread it is your CPU that is the problem. You will see no difference with an OC on the HD4890 or indeed even between that card and the HD4870 when using a 2.0 ghz c2d, especially at such a low resolution.
If you bought the HD4890 in hopes of improving performance I suggest you return it while you still can. The HD4870 is a rather large amount of overkill for that resolution already and the problem was your CPU, not the card. Going from an HD4870 to an HD4890 at that resolution is a waste of money with any CPU really.

Before reading all of that you should make sure your motherboard CAN actually overclock anything. Looking it up that thing is a custom ASUS board for HP machines it very well may lack any ability to overclock at all.
If it cannot OC then your best bet is to do what I said earlier; if you still have the HD4870 then return that HD4890 while you can, or if that isn't possible then sell it. Basically you upgraded the wrong thing. Your HD4870 was not the problem at all and your new card was a pointless upgrade at your 1440x900 resolution(no matter what processor is in your machine.) You should return it/sell it and use the money to get a new motherboard + CPU. You can get an Athlon II x4 and a pretty good motherboard to go with it for about $160 which I'm sure is less then you spent on the HD4890. Paired with HD4870 it will give you very good performance at your resolution.

Intel does make the best processors on the high end at the moment but we are talking a minimum of $300 or so for an i5+motherboard plus you would need to buy new ram because they i5/i7 systems use DDR3.
On the low and midrange AMD's and Intel's processors are basically equal(Athlon/Phenom II vs Core2duos) but the AMD processors are a good amount cheaper and the motherboards tend to be slightly cheaper as well so they will give you the best for your money. Like I said an Athlon II x4 + a decent motherboard would be $160 or so. If you want a quad core Intel chip instead it will cost you that much for just the processor.
As for driver updates replacing your motherboard, whether for an Intel or AMD system, will require a fresh install of windows. All the other components you have now will definitely work however.

Do you not have a Windows disc already? I didn't mean you have to buy it again, just reinstall it.

The e6700 has half the cores and is clocked slower than the processor I am suggesting. Plus your new motherboard would definitely be able to overclock. I believe those chips go to 3.2-3.3 ghz rather easily. At stock it is 2.9 ghz anyway so you wont really need to OC if you don't want to(no reason not to though.)

Hmm, I'm not sure to be honest. It is an HP computer I take it? It may work fine or that disc may specifically be tailored to your current motherboard. Perhaps someone else with experience with HP computers/windows discs can answer that.

Yeah, any Windows will do. Your recovery CD may actually be a Windows CD, HP just doesn't call it that. I honestly don't know, the big computer makers always pull crap like that, making things needlessly confusing. I wouldn't be surprised if it is a windows CD though, just also full of pointless HP software it also puts on your computer. The last time I dealt with one was a long while back but I seem to recall that being the case.

Looking at them again you want the Gigabyte board. I didn't notice when linking them before that the Asus one uses DDR3 ram so you would need to replace what you have now for that one.
Also I notice that one of the reviews for the Gigabyte board says that it has the ability to unlock cores in the BIOS. If you want to you can use that to possibly save some money. AMD sells x3 processors but they aren't actually 3 core processors. They are exactly the same as the x4 chips but they have one core purposely disabled. SOME of the chips have a core disabled because of a manufacturing defect but on most of them the fourth core is actually fully functional. It is certainly a gamble but it's a good one imo. Here's the same board with a x3 of the same speed;
http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
If the fourth core is unlockable then you just saved $30. If not honestly it isn't a big deal. A x3 at 2.9 ghz is still very good for gaming. Some of them are even actually a Phenom II chip with the L3 cache disabled and you can try to enable that also if so but that is more rare.

PC2 5300 is 667 mhz. That is one of the memory standards listed for the Gigabyte board so it should have no problems.

Oh yeah, there is one thing that may differ between your current board and the new one. Most newer boards, including that one, only have one port for an IDE cable because that standard is being replaced by SATA. This means you can only use 2 IDE devices(usually hard drives and cd/dvd drives.) If you have 3 you will need an adapter for about $10.

Unlocking the core would be very simple. It will just involve telling the computer to do so through a setting in the bios. Then you'll restart the computer. If the disabled core is defective it might not start up or the system wont be stable(will crash a lot.) If it doesn't start up the board will likely go back to 3 cores on its own after it fails a few times(at worst you'll need to reset the bios which isn't hard to do.) If it is unstable you can just go back in the bios and turn off the 4th core.
As for the HD4870 vs the HD4890 they should really be giving you the same frame rates. Both are definitely limited by your CPU in that game. I'm not sure why the HD4890 would be giving you less but honestly it doesn't really matter. In that game with a proper processor at that resolution the difference between those two cards would be something like 150 frames per second versus 180 frames per second which is meaningless. The refresh rate of your monitor is likely 60 hz which means it can only actually display 60 frames per second.

No, 60 hz means the screen only shows 60 frames per second. If you are consistently getting frame rates above your refresh rate then it is best to turn on vsync because then the game will match itself to what your monitor can actually display which will give the smoothest gaming experience.

hey about the refreshrate thing is this why i sometimes get low frames in games like insurgancy and hl2dm its crazy i cl_showfps 1 and my frames are like jumpin from 150 to 40 back and fourth constantly same for left 4 dead 2.... io meen thease are simple games 4870 and 4890 should handle them well...

May 10, 2010 4:47:18 AM

Once again it is your cpu that is the issue, not the cards. That is likely caused by there being parts of the game your CPU can actually handle at those points you will see what frame rates you should be getting for that card. But when things start to happen in the game your CPU can't keep up and the frame rate plummets.

Yeah, you'll just unplug the computer and remove everything from the old board. Basically all the cables, the ram and the video card. Other cards if you have any. Leave the processor/fan as you are replacing it. Then you unscrew it from the case and remove it entirely. Then you'll want to install the new processor and fan/heatsink on the new board. Quite easy really. Putting the fan on used to be rather annoying but they've made it simple these day. Then you screw the new motherboard into the case. Then reconnect all the cables. The hardest part of this whole thing will likely be reconnecting the case's power/reset button and lights to the motherboard as the process involves tiny wires being plugged into little pins. The motherboards manual should make it clear where they are supposed to go but it can be annoying. Put the ram, video card and any other cards back in their sockets and you are done.
In general you want to reinstall windows because it has a ton of drivers intended specifically for your old motherboard. While it is best just to do a fresh installation this;
http://www.pcstats.com/articleview.cfm?articleID=1755
Claims that repairing the installation will in fact make windows ok with a new motherboard. It is a bit outdated though and is talking about XP. This describes how to do it without repairing and is how I've seen the process talked about in the past;
http://searchwarp.com/swa548177-How-To-Replace-Your-Mot...
I'd probably do it that way myself because you wont be relying on the HP pseudo-windows for anything. Don't uninstall the ATI drivers though as they will be the same.
As for selling the HD4870 vs the HD4890, yeah, I'd say just keep the HD4870. At your resolution both cards are a rather large amount of overkill. They are both good cards for much higher resolutions than yours(1920x1080.) Considering you will get more for selling the HD4890 the only reason to keep it is if you plan on upgrading the monitor in the not too distant future and even then the HD4870 would still do quite well.
As for which deal to order I'd probably go for the x3 myself as well. From what I've read the 4th core is more likely to work than not and then you get the satisfaction of getting a x4 for much less. Even if the core is defective and can't be used it's questionable whether the x4 is actually worth $30 more anyway. BTW reading some more about that processor it supposedly overclocks very well. The last review I read said they got it up to 3.7 ghz. They used a good aftermarket fan/heatsink though. On the stock one you'll probably want to aim for 3.2-3.3 ghz. Also according to their website the motherboard can even handle AMD's new 6 core chips if you ever want to upgrade to one of those.

If this is your desk top model then you are in the wrong forum, this one is for laptops.



It only shows Vista as your factory OS, so yes your recovery CD's will be Vista. The HP Vista recovery disc's will install with a new mother board. If they don't it won't be because of the new mother board. Some people here have had problems with their recovery disc's being defective or HP has sent the wrong ones.

Alright, I don't know what to make of that to be honest. Just try the uninstalling drivers in safe mode thing from that link. Hopefully it will work and if not maybe those cds will or the partition will.

If you are going from an Intel to an AMD motherboard you are pretty much on your own. Are you installing a standard non-HP motherboard? Certainly the HP disks and partition will not work and you will need a clean install of the OS from a retail DVD.

With an Intel Socket 775 board you would have a lot of upgrade options that would allow you to still work with the HP software.
