OK so i got my E4300 now and i have tested it with the P5PE-VM.
Keep in mind you will need to flash the P5PE-VM to BIOS 1201 before you can use the E4300.
CPU is running @ 9 x 200 = 1800Mhz
DDR runs stock @ 400 Mhz (2.5-3-3/5-7) (not 350 like with E6xxx series)
Multiplier can be only changed to X8 only from what I have seen in the BIOS.
CPU-Z was reporting a 1:1 CPU/DDR Ratio @ 1800Mhz CPU / 400Mhz DDR.
It was also reporting Performance Mode for DDR was disabled so I installed 865Tweaker wich enables SPD changes along with other 865 chipset tweaks. After changing values in 865 tweaker CPU-Z was now reporting Performance Mode "enabled".
I tried some quick overclocking to see how this board / cpu / ddr combination would react. The DDR modules I was using weren't the best OC'ing stuff though I know its stable past 230mhz @ CAS 2.5. ( 460 DDR )
I have some PC4400 DDR that will do past 280 (560 DDR) though I only have one working stick as the other is being RMA'd so i had to mix 2 DDR sticks. ( 1xPC4400 + 1xPC3200C2) They can run stock @ 400Mhz CAS 2.
Using SOFTFSB I raised the FSB to approx 222Mhz. This gave a 2.0 Ghz CPU speed and a reported DDR speed of 444Mhz. Right away sound started to crackle. I have read some other posts concerning the onboard sound / SATA IC's and overclocking. You would have to replace onboard sound/Sata controller with PCI cards if you wanted to OC at all.
I still gave SiSoft sandra a run to see what the performance was as the system overall was still running stable. CPU score scaled up as expected, yielding what it should considering the FSB increase. DDR bandwith on the other hand did not scale at all. You would expect to see more bandwith as the modules were running at 44Mhz higher than stock. Of course you wouldnt expect a monumental increase though it didnt seem to change the memory bandwith at all. Changing SPD timing also made very little difference in memory bandwith performance. CAS 2.5 was actually running faster than CAS 2.0 was (???). I did not attempt to go any higher considering the devices already croaking with a 22Mhz FSB increase. Sandra was reporting a DDR bandwith hovering around 4300 mb/s.
Using a 6800Ultra AGP this system managed to get a 5900 score in 3Dmark 05. This was @ stock FSB / CAS 2.5/3/3). My P4 2.6C @ 3.4Ghz using the same video card and memory scored around 5700. At first you would think that its not a significant difference. Though in real world application, games ran much more smoother and were much more fluid than they were before though this was more noticeable with older tiltles that were more CPU intensive. BF2142 was totally playable and FPS were as high as 60+ on HIGH setting in game video options.
After twiddling with this combo for the last 2 days, even though it was quite fast and very stable, I decided this setup isnt for me.
First of all, if it would at least OC past 250Mhz FSB like any other oldskool P4 865/875 mobo without giving sound/SATA issues it would at least make it worth the $$ as the 4300 could technically go as high as 2.4 Ghz + using some DDR1 that can do at least 250 stock.
Second even if you manage to swap the onboard sound and sata with PCI cards, my tests showed memory bus bandwith wasnt responding to changes in FSB while the CPU was. C2D is already being held back by using DDR1. If OCing isnt yielding any memory bandwith increases you are futher bottlenecking your CPU.
This mobo makes much more sense using it with an inexpensive D series CPU or less for your mom to look up recipies or your dirty uncle that wants a fast porn box. Anyone that would be considering a C2D on an 865/VIA (Dual-VSTA) with AGP would be those stuck with more mature AGP cards though wanting to jump on the C2D bandwagon (like me). Unfortunately although system was much more fluid than it was before it was not significant enough to warrant spending 300$ CAN for this combo for such a moddest increase in scores / FPS. Ive already sold this combo and I am now looking into getting a proper E4300 system (P5B-DX + PC8000 DDR2 + 8800GTS).
