I got the AsRock 775i65G rev2 with the E6300. You can raise the 266fsb up to 300. I would of rather had the Asus, but the manual shows no fsb adjustment on the P5PE-VM. The AsRock manual says the multiplier ratio can be adjusted up or down if it is unlocked, or will be greyed out and read-only if it is locked. My 2.50 bios has no mulitplier section, just blank space? I must say all is well with the new system. way faster and quieter than the old Prescott. Too bad the max fsb is 300, this chip would go much higher...(but my Geforce5900 is the weak link, now)

I just ordered my E6300. Does anybody have an update on the best mobo for overclocking with ddr and agp parts? I need to order something in the next few days. I'm leaning towards the ASRock 775i65G, since it's available and appears to allow fsb adjustment. However, if the Asus board allows any overclocking I'll go that route.

Thanks guys,
Dave

I'm in the same boat. I have a E6400 coming this week and need to get an AGP/DDR400 compatible board. So far the 775i65G looks like the best as it at least allows you to go up to the 300 fsb range. Looking at the P5PE-VM manual I see no where to adjust the fsb from stock.

I sure wish Anandtech would finish up their roundup of these types of boards. They mentioned they would be publishing a roundup soon.

Shipped on Monday by UPS from NJ to FL. I'll post the low down on the Asus board both here and on Newegg's review page.

Someone posted a negative report of the overclockability on this thread of the Asus forum.

I'm betting he had slower than PC3200 ram installed. I'd guess that these boards only have 1:1 and 4:3 memory:FSB sync rates at 266 (1066) FSB. If they (at least the ASRock) a 3:2, then PC2700 should work. I'm not sure, but I'm bettin' that this is the origin of the disclaimer on the ASRock product info page.

"**FSB1066-CPU is supported only when you install AGP VGA card into AGP slot. Besides, if you use a FSB1066-CPU on this motherboard, please adopt a DDR400 CL2.5 memory module."

If LAN speed matters to you, ASRock is 10/100, Asus is 10/100/1000.

If this board wasn't on the way, I'd just say screw it, I'll get a new video card and ram, and get a good newer board.

Built the P5PE with E6300 today. No adjustments for overclocking at all. No ability to get to 14x on the conroe. If you use DDR400 (PC3200) then the E6300 comes up stock at 1.86 GHz.

To investigate some of the other claims of people being exasperated with an underclocked CPU, indeed when I installed DDR333 or DDR266 (PC2700 & PC2100 respectively) I did get a CPU speed of 1.4 GHz.

So, more specifically: no FSB adjustment, no 'CPU Lock Free' feature with this Conroe, no voltage adjustments of any sort. The only thing that you can do is manually adjust the ram timings.

Everything else about the board, I happen to like.

To get to 300 FSB that the ASRock might do represents only a 12% overclock. I personally think I'll hang with this gigabit capable board (I have other PCI cards to fill the available slots) and casually investigate other boards using ddr2 that have good overclocking capability. I'll just have to get a different AIW card.

Like Xvys, I decided on the 775i65G and couldn't be happier. I immediately oc'd my E6400 using the 300 setting and am running at E6600 speeds at low temps on stock cooling. I am running my Patriot DDR400 sticks (the same exact ones used in the Anand reviews of this board) at 2-3-3-7 at DDR400. This was a very cost effective upgrade for me. And when I finally go the DDR2/PCI-E route I will already have a C2D that will overclock nicely I'm sure. But I am going to squeeze as much life out of my DDR400/X850XT as I can for now.

Well, it looks like I'll be going with the 775i65G then. Does anybody know where I can for sure get a Rev 2.0 775i65G? I don't want to get stuck with an earlier revision that doesn't support C2D.

Thanks.

I got a 2.03 rev 775i65G from zipzoomfly (was ordered on 8-28)

So far I am very satisfied with this board and the E6300. I'm reusing 2*512 crucial ballistix and an ATI X800XT AIW.

I wasn't planning on going this route (had planned on P5W DH and E6600) but thought I'd wait it out and see more/better mobos come out as well as have prices drop some.

My 775i65G is the 2.03 rev, also. I updated to the new 2.70 bios with their AsRock Windows installer and it was the easiest bios flash I have ever done. My CPU multiplier ratio reading has appeared with this new bios, but is greyed out and non-adjustable. I guess the C2D is one of the "locked" ratios ;)

I have settled in on 2.5-3-3-7 ram timings. The E6300 is a smokin' processor with a 3DMark05 CPU score 25% higher than any other CPU (incl EE) with the GF 5900XT gpu.

Perhaps they are discouraging o/c on these P5PE-VM and 775i65G m/b's as 266-300 fsb is all they can handle without overheating. Hence the locked dividers, bus, ect. Even DDR-400 ram will run at 355 unless you can o/c.

So, we have three people who?ve posted here after purchasing an ASRock 775i65G (Xvys, cowlickkid, kef7), and one considering the purchase (butch84).

Noone's mentioned the ASRock ConRoe865PE yet, which is better in several respects except form factor (is everyone here in the P5PE-VM topic after a micro ATX board?). Here are the main differences.


ASRock 775i65G
mATX
2 x DDR DIMMs
3 PCI
5.1 audio (Cmedia 9761A)

ASRock ConRoe865PE
ATX
4 x DDR DIMMs
5 PCI
7.1 audio (Realtek ALC850)


I?ve purposefully left out the main difference between the G and PE chipsets, which is that the former has onboard graphics. The reason for this is that the FSB is limited to 800 with onboard graphics. Is anyone really going to buy this board now to use onboard graphics with a Conroe? I don?t think so. Maybe next year when the 800FSB Conroes are out, for those not into overclocking.

I just went ahead and ordered a 775i65G. Who knows when the ConRoe865PE will be available? I really don't need the extra pci slots anyway. I'd be curious to hear about the ConRoe865pe when it comes out though.

I bought the 775i65G because it was available now. I would have preferred the ConRoe865PE if it had been available in the U.S. I did not need the mATX format of the 775i65G.

I try to gather all my findings about conroe865pe or DDR I and core 2 duo mb in general on this simple page:
http://users.telenet.be/oiges/
Anandtech review could give conclusive judgement on overclocking possibilities of conroe865pe and try out clockgen or cpucool to set fsb.

Maybe the ASRock for 775Twins-HDTV R2.0 with its ali chipset is better for overclocking? (only 2 x DDR I , so those with 4 x 512 out of previous pc('s) only have 1 G)
http://www.ocwforums.com/bbs/showthread.php?p=391997 they get it to 340 fsb.

I just purchased the E6600 & the P5PE-VM. I am planning on using my 2 x 1Gb DDR400 RAM, and my AGP Radeon 9800XT. I just got worried that the E6600 wont be compatible with the ASUS, because some sites say that the 865 chipset isn't compatible with the Core 2 Duo. Is that true, or should everything work?

I've also never overclocked, so I'm interested in some mild OC-ing. Any suggestions on how far I can push it?

Sounds like you should have a smokin' machine. The Intel 865 is perfectly suited for the Core2duo. I have the AsRock 775i65G which has the same chipset as the Asus P5PE-VM. This chipset is a couple of years old and is designed for a 800FSB (200 x 4). With your DDR400 ram your board will automatically overclock to 1066FSB (266 x 4). As was pointed out earlier in this thread, with the current bios your Asus board has no further FSB adjustments. You can tighten your Ram timings to speed up your computer, (i.e. 2-3-3-6 rather than the default 2.5-4-4-8). Perhaps with a new bios release from Asus to may introduce some FSB adjustment similar to the Asrock's 300FSB overclock maximum.

okay here's my issue.
while I was at Tiger Direct I got a D940 really cheap, so I also bought a cheap mb Abit SG-80DC . I already had 1 G of RAM(DDR 3200) and a 9250 AGP card from an old computer that died. the new system installed and booted no problem, except it kept crashing and re-booting. I put in a 650W power supply and a GeForce 7600 GS AGP card. and it still crashes every once in a while. I've updated all the drivers as far as I can find. looking on the Abit website, I'm not sure it supports this processor?
so now I found a deal on a Asus P5PE-VM board. does anyone thing swapping everything over to the Asus borad should give me a stable system? I use this computer mostly for rendering video files with TMPGEnc 4.0 Xpress. I gotta tell you, when this system doesn't crash it smokes my old system Aus A7N8X-X, AMD XP2800, 1.5 G's RAM, 9200 AGP, 500W. it took over 5 hours to render a 2 hour AVI (captured and edited on Premiere Pro). to render same file on new system - 1 hour 40 minutes! will this Asus board work or should I just get a different board?
any help would be greatly appreciated.
