Intel Pentium D 940 HUGE BOTTLENECK!

Hey recently purchased a 8800gs and my Pentium D 940 3.2Ghz bottlenecks the crap out of it. But seems on games like crysis, Wanted Weapons of fate there is minimum bottleneck.

Gears of war fps is very jumpy, Left 4 Dead 60fps then zombies come at me 20-25fps, Wolverine low fps too even at 1024x768 25-30fps.

Im a gamer. I was thinking maybe a Intel Pentium Dual Core E2200 and overclock it to 3.0Ghz would solve my problem

Thanks in advance :hello:

Providing your motherboard supports the E2200 it would be a reasonable upgrade. L4D likes a good CPU, and Crysis really needs a dual core to run well (otherwise it will run with consistent but low FPS), but I can't speak for the others.

e2200 @ 3.0 will help alot. So would a new GPU, the one you got is a piece of crap.

8800GS.... piece of crap? its best price/performance for my budget i heard overclocked it can get equivalent fps as 9600GT. Thanks for the advice

Nope its crap, but if you got a certain budget theres not much you can do.

Oh come on. The 8800GS is not a piece of crap. The 8400GT is a piece of crap. The 8800GS is outdated, but it certainly has enough power for most modern games at medium settings, and is probably not the bottleneck in the system mentioned.

Oh, and the Pentium Dual Core series would be a pretty significant upgrade. It should help a lot.

The OP is not looking for video card purchasing advice, therefore none of you are helping. The 8800GS is a decent match for a Pentium Dual Core, and while a new card would help, it won't until he dumps that crappy old Pentium D. He could throw a HD4870 in there with little benefit. It's all about priorities, and you're just confusing his. Also, the 4650 is not 3 generations ahead, it's only 1 or 2.

The 9600GT will still beat an 8800GS when Antialiasing is turned on unless it has a rather heavy overclock, but under most conditions the 8800GS is such a monster overclocker that it can outrun a 9600GT. I would ensure you have at least 2GB of RAM as well, otherwise you'll find you get stuttering with higher graphical settings. 4GB would be preferable, and RAM is cheap right now.

CJ,


A 50 dollar 4650 would probably whip its ass on stock clocks. We're talking about 3 generations ago. That's a LONG time in videocard's. :lol: 

I still have a 7950GX2 that gets its ass kicked by my 4770


I know perfectly well what an 8800GS is. It's a G92 part, which makes it one generation old (the only newer gen is the GT200). Yes, I know Nvidia has renamed the darn things six times by now, but it is actually only a part from one generation ago. At the time it came out, ATI was on its HD3000 series cards, and now they are on the HD4000 series. Therefore, ATI is also only one gen ahead of where they were at the time of the 8800GS. It was a semi budget card at the time, true, but it is (as I said before) far from crap. Besides, it overclocks beautifully.

(I'd be somewhat surprised if the 8800GS couldn't beat a 4650 on stock clocks, btw, seeing as the 9600 thoroughly destroys a 4650 in every way. The 4670 is probably a better comparison)

May 17, 2009 10:44:40 AM

^ no the 4670 has double the stream processors.

and 8800gs = 9600gso. Well actually they have the same gpu's but the 9600gso has more vRam.

OP what is the mobo you have in that rig?

Might help in terms of what CPU will support it.

An old 65nm part which you can easily overclock sounds the go.

Many of the older boards wouldn't support the higher clocked dual core orquad core cpu's due to the power regulators.

Throw the mobo detail this way and we will see what suits.

random and cjl's graphics advice is sound too ...

I'm sorry, but I find it hard to believe that a P4D can't fully power the 8800GS/9600GSO. (the real model of the GSO has the same amount of Vram as the 8800GS, 384MB) The 940 is a true dual core chip, and I would think could fully power a midrange card. I would love to see full system specs before I start telling him to get a new CPU. For example, if he uses Vista and has 2GBs of ram or less, I'd start there.

Stock, its 9600GT > 8800GS ~4670 > 4650. High overclocks, GDDR4, etc can change this.
a b à CPUs
May 17, 2009 2:17:35 PM

Are you kidding??

The 940 is nothing more than 2 P4's stuck together with a bit of smoke and mirrors.

The X-Bar is primitive and the architecture flawed due to the poor cache design among other things ... in particular the Replay MUX which was a disaster ... causing a dramatic drop in IPC due to the cache endlesly cycling.

Even an E2200 would waste a P4 dual core ... runnning at half the speed.

May 17, 2009 4:39:02 PM

I didn't mean to imply that the 940 is a great chip, I merely mentioned that there are two real cores on that chip. Most P4s show two cores due only to the Hyper Threading "trick" that they do. The 940 has two (slow) cores. This makes it faster then the 5xx and 6xx P4s that many people bought.

They might be slow, but again, they should be capable of power an 8800GS. Putting in a faster CPU isn't going to boost his FPS by 25%+. I would like to know what he has in his system, perhaps there is something else causing his slow downs.
May 17, 2009 4:49:08 PM

I have a shitty motherboard atm, my gigabyte has gone for repairs. My 2gb ram has to declock to 533mhz on this mobo, its 800mhz on gigabyte board. ECS RC-410 asterope 2. Will it perform better on the gigabyte board it supports core 2's, quads, all pentiums 4+. ECS can't overclock anything besides graphics, but on the otherhand gigabyte board can. :D 
May 17, 2009 6:17:08 PM

The pentium dual core would help a lot especially if you can get the E5200.

As for the 8800gs, is it the one with 96 stream processors, or one of the modified ones with 48?
May 17, 2009 6:27:26 PM

96, but overclocks madly.
May 17, 2009 6:39:46 PM

hi guys!

in 2008 i got this pc:

PD 945 @ 4 ghz

Kingston 667 @ 630

Ati Radeon HD 3850 256mb

in lots of games like l4d my fps when the zombies explosions etc.. appear my fps simple go down

when i upgraded it to a Q8200 im l4d counter-strike source and other games i got a good FPS RISE

in CSS something like 50+ FPS and l4d 15+ ( o.o )

so the Bottleneck is that Damm piece of crap Pentium D u.u

( sorry about my english xD )

what are you talking about ,i have a Penitum D 950+a 9600gt and crysis runs brilliant @ high details.
May 18, 2009 12:18:20 AM

With the 96 sp's, that 8800gs surely is not crap. Just make sure that if you do get the E5200, you make sure that your motherboard is compatible.

May 18, 2009 1:43:05 AM

Just make sure that you Pentium D are not overheating. Those were pretty good space heater and would overheat easily when pushed hard in a case with bad airflow, or a clogged heatsink. Even sometime, the cooler would loose contact on the cpu, making it to overheat.

first, make sure you have good airflow in your case, that the cpu heatsink is not clogged and it is making good contact on it by pressing the 4 plastic pins that hold the cooler into place.

this will make sur that your cpu is not throttling down its speed because of overheating, causing bad performance at gaming.

My dad runs at 1680x1050 on Very High DX10 on an 8800GTS 512MB and a Q6600. He gets about 15FPS, but to him that's "brilliant." The OP is not finding it "brilliant," therefore he needs to upgrade. You can keep your dinosaur as long as you want but just because you think it runs fine doesn't mean everybody else does. You have in no way helped the OP. However, you did manage to double your post count which I'm sure makes you feel great.

wrong. the 4650 has the same number of stream processors as the 4670 which is 320. The 4650 just clocked lower. Just like we would have the 4850 and 4870

Helloworld_98 said:

The HD4650 and HD4670 both have 320 stream processors. The main difference is that the HD4650 usually uses GDDR2 instead of GDDR3, along with a slower core clock.

Not necessarily, there are multiple versions of the 9600gso. Some are just an 8800gs with a new sticker, some have 768MB of RAM and some of them are neutered 9600GTs with only 48 stream processors.
May 18, 2009 7:29:49 AM

Lol its like a video card debate. And for anyone who says 4650 is better than 8800GS stock 4 stock i want to see a benchmark to prove it. Lets get off graphics card discussion. I now have rounded it down to this E2180 VS E2200 VS E5200.

Good pickup there pat.

OP check your temps as the firebreathing CPU you have there might be throttling due to a thermal problem.

Check temps at idle and under load.

Let us know how you go.

Reseating the CPU with new thermal paste and blowing out the HSF with some compressed air before reattaching is a good move.

Your Pentium D is holding you back.
Guys, that Pentium D is FULLY 50% slower than an old X2 Athlon at the same clock rates.
An "older" core 2 duo is 15-25% faster than an Athlon X2....in other words all the people here who are saying dump the PD, they are right on. Yes, it will even be bottlenecking a 8800gs. The PD may have been a decent processor in it's day, but it is a 3 legged turtle compared to todays processors. Yes it is time to retire it!

Of course you know, a lot of folks think their system runs "brilliantly" with a PD because they are ignorant. And it's not their fault at all, they simply don't know any better.

Keep the system specs coming. Perhaps by post 56 we can get a clear picture of what we are dealing with. What we know so far,

P4D 940
Motherboard is junk, but we have no idea what it is
RAM is 2GB (2x1? 1x2?) running at 533MHz
GPU is the 8800GS
Harddrive is unknown
PSU is unknown
OS is unknown
Resolution is 1024x768.

The P4 is a good candidate for the low scores, but with no 3DMark 06 scores we have no idea. (broken down please if you can/care) It might also be a ram problem if your using a single 2GB stick and are running Vista. It could also be a power issue if your PSU is really old and its struggling to power the P4 and the 8800GS. (which does use a 6pin PCIe plug, or at least mine does.) As I said in my first post,

Always try to get a clear picture of whats going on before telling people how to spend their money. The P4 might be the issue, but there are other possibilities as well.

Next I'd like to know if your P4 is thermally throttling or not. Check out this link and see if it is.

Might want to run the program, game for awhile, then exit out of the game and see if it did. Perhaps you just need to dust out your computer.

Whoops, been a long thread. I guess I give the P4D to much credit. I mean even my single core 3500+ was able to play TF2 at 1280x1024 with an x1800xt. Wouldn't a dual core P4 and a faster 8800GS at 1024x768 be able to do the same? I still think there is something else going on.

Eh....I played that game at 1440x900 so yeah its faster. But its not enough. Thread been going for a long time lol. And for the guy above my comment MY PD doesnt get hot for some reason ive never seen it past 53C so no heat problem. I think of narrowed it down to RAM at 533Mhz being the problem.
May 20, 2009 2:33:43 PM

Wrong. Your motherboard supports ddr2 800 mhz but doesn't have to work at that speed . Everything is acutally related to your cpu. Your cpu has 200 mhz psp (FSB 800) and your ram is actually 266 (533 mhz). So actually if your processor is syncron with the ram memory (should be syncron), everything should work at 200 mhz. That will make your ram working at 200 (400 mhz) so lower than 533. So your ram is NOT the problem.
May 20, 2009 10:45:56 PM

Your GPU and CPU are fine, i think you should upgrade your Rams if they aren't already 800mhz

May 20, 2009 11:51:55 PM

As hefox correctly said, he doesn't need that speed. 200MHz FSB x 2 = DDR2-400. He has better then that.

Any chance he has the good temps because its throttling? I'd run the program seeing as its free and won't harm anything. As I said, I've played TF2 on a slower CPU and GPU at 1280x1024 and didn't have any problems. (1600x1200 wasn't playable.) Dropped a bit in very heavy action, but I could still fight. TF2 should perform about the same as L4D? It really seems to me that he should be fine, perhaps the P4D is much worse then I remember.
