asus p5kpl-cm and e5200 overclocking problem!!!

I've used that board a dozen times for customers. I've always used 800 ram. Your right about the divider and your right about setting it to 667. You've done everything you can for the setup you got. With 800 ram 250/260 is the standard limit that board will go on the FSB. I believe you could get a little more with some 1066 ram, but your better off getting a Asus P5Q instead so you have the full options, and keep 800 ram.


Also on a side note I've seen alot of reviws about the e5200 OC is kinda hit and miss. It may not go much higher as well, but then again you might get lucky and get 4.2. Your best shot would be on a better mobo.

Thats what I would do, if you reallt want to push to the limits. Its a great board, just not a miracle worker. I just got my son a P5Q. I was gonna get the P5Q SE, but it only has 4 phase voltage, where as the P5Q has 8.

I got a friend that has a P5Q Deluxe with 4g of 800 ram for sell for $200. That is a steal if your interested, also the deluxe model has 16 phase voltage. PM me if you want to get in touch with him.

Well I'm on my moms new P5Q-EM right now, and it is a real impressive matx board. I got a e1200 in it 1.6 Overclocked to 3.2. 100% overclock. It is running Visat 64 with 4G of ram and it can play Blu-ray rips just fine.

I've seen people having issues with dedicated Video cards, but I use onboard video so I can't tell you.

We actually sold that mobo ram combo for $150 on Ebay last night.

1.35

Cool. Your temps are about 10c better then mine cause I'm using stock cooler LOL. I tightened my ram to 4 4 4 12 also. I; ve had this thing for 2 weeks wish mom would come get it. Ima have it wore out before she sees it.

LOL. My mom is 58 and she need it all. My son is gonna be 8 and I just ordered his rig with a e8400 E0, and ima try to get 4.5 or so out of it. It is for his B-day next month. His system will be hella sweet when it is built.

Pretty much. I was gonna get a 3.6 quad but none of his apps are threaded, so I figure I get him the fastes CPU I can get him. And the e8400 E0s are hitting 4.5 on air. I got him a ati 4670 to watch his movies also lol, almost bought him a 4870, but I talked myself out of it.

Ya I think it looks like you got a good chip. I wouldn't be suprised if it hits 4.0. Let me know how it works out for you, I'm curious.

I was gonna start using them in budget builds but like I said some hit big numbers, some dont. Your already higher then the some who dont, so I think you'll be fine.

I almost prefer a chip with lower multi so I can run somewhere between 400-500 on my FSB. I think alot of the e5200s have FSB limitations.

Do the BSEL Voltage mod.

A 450x9 will be lots faster then a 12.5 x 320.

I really doubt this chip will run 450 though no matter what.

You use a conductive pen or some window defroster repair kit and connect a line between certain pins on your cpu. Google it.

You can do it for voltage and FSB.

Ignore this guy... Anyway, thanks for the advice roadrunner! I booted at 3.88 ghz (12.5 x 310 fsb). I got the voltage to work, but I'm not too sure about the fsb for the processor kicking in. As my memory is still somewhat being pushed to it's limits, now I'm seeing a limit for the RAM for sure, as this cheap centon ddr2 800 is being pushed to ddr2 1034.

Not bad, I might just clock down to 3.6 ghz as the temps are now rising a bit. The mobo temps only went up a few degrees. As for the processor, well a good 8 degree celcius, but that could be because I didn't bother to apply new thermal paste, LOL!. But the temps aren't too crazy. Looks like I might just get that Ram after all...

Now to make sure that fsb mod is working. That aluminum foil rubbed in the sticky post-it stuff should have worked... LOL!

Edit: Damn I think the example with the sticky foil was shown with the contact with no sticky stuff. That's really nitpicky... Back in thirty mins...

3.75 ghz stable 12.5 x 300 fsb. Can't seem to find the fsb mod as the RAM divider lock is still holding me back.

Last edit : I am now running at 3.84 ghz stable. Not a bad oc, probably end up just getting better cpu cooling, RAM and oc back up to 3.88 ghz to keep it stable.

can anybody explane me how is he able to set fsb to 300 if his ram was 800 Mhz? The only 2 ratio for fsb:ram are 3:5 and 1:2 with this Motherboard, please help me

I just bought this board a week ago. I could not get the BSEL mod to work with this board and my E4300. My P5L-VM worked for BSEL and had better FSB settings and cpu voltage adjustment. Only reason I bought this board is becuase the P5L-VM tops out at 289fsb and I wanted to go 333fsb.

The only thing that works for the E4300 and this board for me is using the AI overclocking. 20% works, but 30% doesn't. I have not messed with the voltages of the memory for the two voltage settings of the CPU.

I'm not sure if the habitat87 guy got the BSEL mod to work or not, he didn't say.

This board is really poor for the FSB capability, and thats why its so hard to overclock. It only likes certian ratios internally. Its not really the bios setting.

The 45nm CPUS may overlclock better then the E4300 65nm I have.

The E5300 2.6ghz just came out I may be getting one of those or a E8400. I will post back when I do something.

Bicot, wow you got the BSEL mod to work? I could not get it to work. IT would not boot with the 200 to 266 strap. And it worked on my old Asus mobo. Maybe this board only likes the 266 to 333 mod. hmm... Dang I should have tried that before I bought my new mobo. Long story short I ended up buying a Foxconn G45M-S with onboard raid, it it rocks!

With the P5KPL-CM you pretty much need 1066 memory to do any decent overclocking. And it has to be a low latency at 1066, like 5-5-5-15, because the motherboard can't do higher then 6-6-6-15. You have to use the 667 memory setting to get the 3:5 ratio, and the 800 setting to get the 1:2 setting no matter what everything else is set at. Just like Bicot said there is no PCI lock so you need to stick to the standard ratio, that means no small overclocking adjustments.

Possible safe ratios with the 200(800mhz cpus):

200 fsb chip with the memory actually running at 800 or 1066mhz:
240cpu, (with 800 memory set with the 667 setting) = 1.66(3:5)
320cpu, (with 1066 memory set with the 667 setting) = 1.66(3:5)

Caution according to manual and according to the post of Bicot:

Recognition of FSB and the respective external clock speed for system bus and PCI bus is fixed. So for a 800 MHZ FSB, 200 MHZ is sent to system as well as PCI bus and OC will directly change the PCI as well.

So i am downgrading to 227 Mhz to keep my PCI bus below 38.

For 1066 FSB, 266 is sent anf for 1333 333 is sent.

I know this thread is dead, but I have the same combo p5kpl-cm/ e5200. My prob is oc'ing the ram. I can't seem to reach the advertised 1066Mhz.

CPU-z = Memory Frequency 533.3 MHz (1:2).

I have the DRAM Frequency = 800
and the voltage @ 2.25

I am using Gskill pc2-8500
2048MB * 2
CL 5-5-5-15
2.0~2.1v

Any advice Please?
