System is stable and I’m happy with the speed of the cpu, just want to get the ddr2 to run as it should and this is where I’m stuck, my ram is only running at 800mhz, I’ve tried getting the dram voltage up to 2.2v and changing the system multiplier to 4.00A which gave me Memory Frequency at 1066mhz but my system won’t start, it just keeps restarting itself … I’ve tried many different ways to do it (voltage up and down, changing timing to 5-5-5-15 as kingstone recommends, lowering cpu host frequency, etc) … and always the same thing happens, system won’t boot … Help !!

You need to up the voltage on your memory to 2.1 - 2.2v then change your dram frequency to 1066, make sure mem & cpu aren't linked. Someone with one of those boards will pop along and tell you better.

Biffa · 16 Jul 2009 at 09:16

You need to change the:

System Memory Multiplier ..............:[3.00A]

To 4.00 (266x4 = 1066)

But as Deuce said make sure the memory voltage is correct for the DIMMS you have.

I have a similars setup (see sig) - i can't get my memory stable over ~900Mhz (depending on clock) with the system clocked - it's not unusual and to be expected when clocking the e5200.

Some ppl have achieved it but most have to run their 1066MHz memory below stock. I bought the Kingston 8500 knowing this but i knew it would give me a bit more flexibilty with my clock.

I opted for a relatively high clock and sacrificed memory MHz as the benefits were greater in overall performance. In comparison you'll notice the extra benefits of a 0.7Ghz (3.2Ghz) clock on the CPU but you won't notice the difference between 800Mhz and 1066Mhz in day to day usage.

Hello all, thanks for a quick reply.

I've tried that, dosent work. It also crashes if I up the multiplier to overclock the cpu, after i start a blend test with prime95 system just reeboots ...

Plec what settings do you use to get it to 3.5 ?? did you lower the cpu clock ratio and up host fequency ? Or do you have the multiplier set to 12.5 ? Also if you can tell me what voltage do you use ? Thanks in advance

Plec · 16 Jul 2009 at 18:02

A quick reply as I’m in the process of DIY – which I hate – so this is a convenient distraction.

Sure - but, unfortunately there is no guarantee it will work for you as, you're probably well aware, even when using like-for-like compnents their ability to clock will usually vary slightly, sometimes majorly - but it will give you something to work on.

If by some happy circumstance is does works straight off – prime95 it for a few hrs and if it passes then incrementally lower voltages until it buckles and then go back to the last known stable setting. Oddly, I haven’t done this yet for my 3.5GHz because I just bumped the vCore down to 1.3v from my 3.8Ghz setting and I was fortunate enough for it to work – I plan on finding it’s lowest, stress stable limit when I’m back from holiday.

Aaanyway, here are my (present) settings:

Multiplier - x12
FSB - 292 (i rounded it up for convenience)
PCI-e - 101
Memory Divider - 3.33C (973MHz)
vCore - 1.30v (I reckon I could get a lower stable voltage but I’ve yet to experiment. I’ve dropped from 3.8GHz to 3.5GHz since the summer kicked in as the 3.8Ghz became, at first, a bit unstable but then became too noisy to justify.)
DRAM - 2.2v (This I know I can run lower but it’s set at 2.2v because my memory is so close to 1066MHz – and again I haven’t had time to stress test the 3.5GHz clock properly.)
Timings set manually - 5 5 5 15 (You should try 5 5 5 18 first – use 15 once the system is stable.)

The system idles at a rather warm 49º but this is made irrelevant by the load temps which are 67º - i should really get a better cooler but as the load temps are ok i'm going to just ride out the summer at 3.5GHz.

Let me know how you get on.

djkingceramics · 16 Jul 2009 at 18:03

I have a very similar setup (4 weeks old) & would love to find the answer, I cannot cold boot at 1066 & am running at 800 with the multiplier at 12.5. Cpu @ 3.33 GHZ
memory (Corsair 8500) at 2.1V but not stable on 1066 or cannot cold boot. I bet it is a simple answer but after a lot of Bios tweaking & internet searching I could get it to cold boot at 1066. For me running at 1066 was much quicker but no use if it will not cold boot up every time. Maybe needs a better CPU sometime ?

Plec · 16 Jul 2009 at 18:06

djkingceramics, try a clock without using the 0.5 multiplier - i found that i got better results when only using 'whole numbers' where the multiplier is concerned.

I found that my 'experimental clocks' were more prone to fail with the 0.5 option enabled.

djkingceramics · 16 Jul 2009 at 18:26

Thanks Plec I'll try the 12 multiplier & see how it goes.
Hopefully we will all get stable faster systems soon. Looking on other forums I found other people struggling with cold boots with the memory over 800 but no answers.
Update:
Using Plec's settings CPU @ 3.5 & memory @ 974 - windows is much more responsive & games quicker.
Started on cold boot fine - lets hope it starts in the morning.
CPU temp at 30/31C
This is what makes the Overclocker forum so great with helpful input.

Plec · 16 Jul 2009 at 18:41

No problem - hopefully you'll get some better results.

I found manually setting the PCI-e setting to 101, also, helped - i forget the science/reasonong behind it - but it helped balance my setup, epecially when i was pushing past 3.8GHz.

Great result - hopefully it will pass the cold boot test.

I'm very envious of your temps @ 3.5v - what have you got strapped to the CPU?

djkingceramics · 16 Jul 2009 at 19:02

I have just a cheap Arctic Cooling Freezer 7 Pro CPU Cooler
but it seems to do the job. I'll run prime95 & see how it goes.
Really pleased so far & games sure run a bit quicker.

Thanks.

Oddly enough, since writing out my core BIOS settings i lowered my vCore and prime95 the system. I run Real Temp at the same time, for obvious reasons, and noticed that i have quite a big discrepancy between the 2 cores (approx 10º) - so i think a push-pin may have worked itself loose.

Looks like I’ll be fixing the bolt-thru kit I bought, to replace the pathetic push pin method, when I come back from holiday – as my higher temps and instability @ 3.8GHz may not be due to the summer heat after all…

Passed cold boot test

- happy now with 3.5 & faster fsb/memory. If I get temp issues I'll go for a bolt-thru kit. Next job is to dual boot with windows 7 & XP & see how good windows 7 is.

I've tried the settings, system boots but when loading windows i get a blue screen every time, lowered fsb till 270, system did boot into windows but after 2 minutes it failed prime95 torture test :confused:

What do you use for MCH voltage ??

I don't know what to do anymore, my fsb is at 1080 atm, maybe this board don't like anything higher then that, i mean it can play whatever i throw at it with 3.2ghz, but i want MORE .... hehehe

Did you test your new settings with prime95 ??

Ran prime95 for 60 mins (blend setting) & all was fine.

Starting fine on cold boot as well. played a couple of games for 40 mins & all okay. Looking good so far.
The p43 chipset does seem temperamental with the e5200 cpu. It is worth trying other settings for that little bit of extra. 3.5GHz is the sweet spot apparently to aim for on the e5200. Good luck.

It will be a combination of factors - but you may have a, relatively, poor clocking chip - maybe. For now lets just presume that you haven't quite got the right balance of settings as that is, hopefully, the more likely failing.

blamic said:

I haven't had to touch the NB but you can safely knock it up a couple of notches if you want to test it.

What vCore voltages have you tried? My vCore is comparatively low compared to other ppls settings - so don't be scared of bumping it up significantly from my setting.

Additional: and remember to try the slacker memory timings first and manually set them.

I've only went up to 1.325v, how far should i go if i want to clock it to 3.5ghz ?? and what timings would you suggest ?

Hi if it helps my cpu volts are 1.352V & Mch Core is 1.22V
Corsair 8500 memory @ 2.1V, maybe increasing the votaltage will help you achieve an higher clock. Good luck with it.
Your post has given me a performance increase from 3.3 to 3.5 & memory from 800 to 974 & the pc is now much quicker & the graphics faster due to increased speeds.
