805 vs. 930 and Overclockin

[GeNome]

Right now I could afford either one, but the 805's $130 is mighty tempting compared to the 930's $210. It will be used for multimedia/multitasking stuff, which is why I'm getting dual-core, and it'll be used with 2GB Corsair VS 533, X800XL, Asus P5WD2 Premium and most likely an AC Freezer 7 Pro, unless there's a comparable/better cooler for ~$40-50. I'm not new to OCing, so that would definitely happen. Thanks!

Hold it if you an wait 6-8 weeks you can get Conroe For ~$250 and it will be much better then an OCed 930. If you must have it now then the 930 is way to go.

Well, I don't mind staying 1 step behind the latest hardware as it usually saves me quite a bit of money. It needs to last me 1-2 years until the mobos/CPU's are down in price.

If you are geting a new mobo and ram anyways then geting Conroe based system will not cost you more then an extra $100-150 and it will last longer then 930 will.

Yes, conroe is the way to go if you can wait. If not, get an X2.

 

[GeNome]

Well, I can't get an X2 because I already have the DDR2 RAM. Conroe looks pretty nice..but I need the comp ASAP, and I'm only a student so I don't need top-of-the-line stuff. So keeping that in mind.

 

[Markfw]

can't trade the ddr2 for ddr ?

You could get a yohna cpu and new mobo and oc it 2.5 to 2.7 and that will be on par if not better a little better then X2 at the same speed.

Too bad that Aopen motherboard costs $300, the other boards are unproven so far, I am still planning to get the Asus N4L-VM once I sell my dothan.

OP, if you are planning to get the P5WD2 premium anyway, go with the 930 over the 805. The 805 runs very hot, and is difficult to overclock on air, the 9xx series runs a lot cooler.

I got my 805 running at 3.5 Ghz on default vcore and am using the XP-90 with the SKT775 adapter kit. The rig idles at 42 degrees and loads in the low 60s. I made my rig to encode video and am very happy with the results. The 805 and XP90 will run you about 165 total which leaves a nice chunk of cash for other uses.

Update: My mom agreed to pay for the extra cost of the 930, so I got that. So far I've ordered the P930, an AC Freezer 7 Pro and an Enermax Liberty 500W from ZZF for $350. There's a guy I know that might be selling an Asus P5WD2 Premium for $145, so I'll get that if it works, but if it doesn't go through which mobo would you recomend for under that price?

Try for that P5WD2. It's one of the best overclocking boards you can get for your 930

There really isn't another board I can recomend, since you want to get a good overclock. I tried 5 differant motherboards and none of them could get a good OC with the 9xx series, only good results I have seen are the P5WD2 premium and P5WD2-E premium. The 945 chipset boards all seem to have a PLL linked to the PCIe bus, so you have to OC the PCIe bus to get past ~225mhz FSB, which then causes the entire system to become unstable. My NF4 Intel edition board did the same thing around 225mhz FSB with a 9xx chip, but was able to hit 250mhz FSB with a single core P4. My P5P800-SE doesn't get the stuck FSB, but still doesn't get me past 3.43ghz stable(probably because it has no chipset voltage adjustment).

P5WD2 is a great board, 805D @ 4+ Ghz on it

P5LD2 if you need something cheap (115$)

Except the P5LD2 has the stuck FSB problem around 225mhz..

 

[Absolute0]

my friend has a 630 @ 4 Ghz on the P5LD2, how is that possible with an FSB problem at 225?

Yep here's one of his posts

Stevty where are you getting your information that P5LD2 craps out at 225 fsb?

 

[kyleslater]

Screenshot @ 4.2Ghz

And of course CPU-Z validation

The P5LD2 supports the XE editon chips and the 266 FSB just fine. It is also rated for 450 MHz but rarely does anyone get close to that. If someone is stuck @ 225 then it is Ram issue or something like that. (possibly something that does not like the PCI bus raised or the PCI-E is holding something back).

Thanks for coming by and clarifying that

So it looks like P5LD2 for 115$ overclocking board and a P5WD2 for 150$ overclocking board.

It doesn't happen with the single cores, it happens with the dual cores. It's a problem I had, that everyone else was having with the same board, and basicly any board with the 945 chipset. Some one else on the forum showed me a way around it by increasing the PCIe frequncy. 110mhz allowed me to get to around 235mhz FSB, 115 got me to 245mhz FSB, and 120mhz got me to 265mhz FSB, but setting the PCIe past 110 made everything unstable, the graphics card would get artifacts. Tried this with 3 other 945 chipset boards and the same results. Again, this isn't happening with single cores, only with dual cores, both 8xx and 9xx series. The 805 works fine, because it starts at 533fsb, and isn't reaching 225mhz FSB even on water.

EDIT: also note, the board did not allow overclocking past 265mhz FSB, it will only enable 266mhz and above if you are actualy using a CPU that runs on the 1066mhz FSB hence my failed attempts at a BSEL mod.

 

[Absolute0]

While it seems that a 900 series and P5LD2 may not be a good OCin match, we know that at least on single cores it goes past 265 cuz Kyle just showed ya 280 with a 630 which is normal 800mhz fsb not 1066 like you say is necessary

I did actualy try my single cores on the same boards, and they did not have the problem, it was just my 830 and both 920's. I only tried the PCIe trick on 2 of the boards, and it worked both times, but again past 110mhz, the graphics would wack out.

EDIT: also, same thing with my 920 on my 8N-SLI, wouldn't go past 230mhz FSB, but my single core ran at 250mhz FSB(posted higher but not stable, but most likely the CPU), and my 805 is running at 3.7ghz on it(185mhz FSB). So perhaps it's something incorperated in to the CPU itself, that the 955/975 chipset boards can bypass.

These are the ones I'm considering right now:

EPoX - $108
Asus P5LD2 - $117
MSI 955 Platinum - $156
Abit AW8 - $109

I'm kind of concerned with the Abit, Asus and MSI because I don't know if they'll support the 930 out of the box, and I don't have another P4 to flash it with. So...

Any of the boards should support it out of the box since the 9xx has been around for a while now, any of those boards should have a recent enough BIOS. I would probably go with the Abit AW8.

 

[GeNome]

Ok, well, if any of them should I'll go with the Abit. It turns out I can't get the Asus Premium anyway. :/ The Abit was my original choice though.
