You will not get PC2 8500 ram running at full speed with a E5200. Pointless putting it in that bundle if you ask me. With my E5200 running at 3.6Ghz (12.5x280) the ram only runs at 960mhz even on the highest divider. 1.8v is too low for a 8500 kit. They are usually 2.1-2.3v but you will need to check the box for the correct voltage.
 
They probably have set the memory at 800MHz deliberatly as the system would become unstable if they had tried to run it anywhere near its designated speed with the CPU clocked.

I have an almost identical system (see sig) and i have to run my memory just under 900 MHz (or over can't remember) - to get my system stable.

You could try upping the memory frequency via the ram divider and respective voltages but i would check with OC's first as this may effect your warranty in getting settings altered over the phone... (But TBH, there is no point as you wouldn't notice any difference.)

The thing you could try, at a later date, when you're more familiar with your BIOS settings, is getting more MHz out of the CPU as it's quite possible you may be able to get 3.5GHz or more out of that chip...

Just read the description of the ram;
"Each module pair has been tested to run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-18 at 1.8V."
So id only get 1066 @ 2.2v

Yes, if you had a mobo and cpu combination that could run it at that speed. However, you wont be able to achieve that even if you applied the settings.

I'm running my memory at 2.0v @ ~940Mhz - that is the maximum i can achieve with my E5200 clock.

I would leave your settings well alone for now and get accustomed with your system and its quirks - and its BIOS.

Only then should you consider upping your CPU clock or the memory frequency - but i would be inclined to leave the memory settings well alone and just concentrate on the CPU (when you do decide to experiment)

Erm Ive got that kit and running it @ 1066mhz with 1.8v on a DFI X48...!!:confused:

The memroy will run at 1066 with the right mobo and cpu combination - just not with a p43 chipset combined with an overclocked E5200 which has a default FSB of 800Mhz. (The E5200 being the main problem.)

Okay, Ill leave the ram alone then.
How easy is overclocking the CPU then?
BTW, this is my first computer build, and first time overclocking....

Pretty simple once you have a basic understanding of your BIOS and its settings.

I suggest you live with the pre-set clock you already have set for a week or so. During this time use and abuse it with games and apps just to be sure that it's stable.

In the mean time familirise yourself with the BIOS and read this overclocking guide - link. Once you're happy that your system is stable and you're a bit more clued up with the BIOS/clocking guide - come back and we'll try and get a few extra 100Mhz out of the cpu.

Hope it remains stable and I shall look out for your post.

On a side note - you need to reduce your sig to just - '4 consecutive lines of normal or smaller text' - otherwise you'll have the forum mods knocking at your door. ;)

Here's a link to the sig guidelines - link

No need to apologise - it was just a bit of friendly advice to save you some grief.

Sig looks fine, now, and will be useful info for when you want to experiment with your overclock as we'll have your spec infront of us.

Hey Ryan111,

I think that's a real nice *Bang-for-Buck* bundle you bought there, just needs a nice GPU added and you got some serious gaming ahead of you!

I just wanted to say it is possible to get DDR2-1066 Memory running at full speed alongside an Intel® E5200 processsor but it does require some knowledge and a lot of fiddling/testing which some may find offputting! :)

As the lads have already stated the low natural 200MHz FSB of your processor (Quad Pumped for 800MHz System Bus) tends to throw a spanner in the works as I believe most modern LGA775 motherboards are expecting a processor using a 266MHz-FSB (Quad Pumped for 1066MHz System Bus). WHat I am saying is most of the BIOS's are tweaked and refined but I think the BIOS engineers put more effort into the areas that will be used by the majority of end users while the more exotic hardware gets just a quick dust down and is mostly functional but certainly not as refined as it could be.

One of the problems I found when first playing with an Intel® E5200 was the motherboard was [Auto] configuring a lot of internal timings very aggressively to compensate for the chips natural low 200MHz-FSB. This is not a problem until you start trying to overclock either the CPU or FSB or begin tinkering with the memory and then *bam!* you have crashed!

If you can get a bit of Theory in and improve your understand of how the FSB-Straps and the tRD setting works along with knowing which voltage needs pumping then I'm sure you will be able to get a nice all-round overclock going on!

I include a couple of sceenies from the last Intel® E5200 testing I did, this was with a nice 2GB DDR2-666 kit that could overclock well and the ASUS P5Q-EM motherboard which is a microATX jobbie using the Intel® G45 express chipset . . .

It certainly wasn't the most MHz I could get from the processor but alongside a 266MHz-FSB (Quad Pumped for 1066Mhz System Bus) and DDR2 running at 1066MHz I found the end result a more balanced system!

Good luck with your overclocking and post back if you need anymore help! :cool:

Interesting post, as ever, Big.Wayne.

I think our problem is more the p43 chipset combined with the E5200 where as the p45 combination tends to have a bit more flexibility.

I've had success getting 1066Mhz on a p45 chipset with an E5200 (lower clock than yours - Kudos) but i've yet to achieve it on a p43 chipset.

Have you had any luck with a p43 and E5200 combo? - as although the benefits of gaining the extra ~100MHz from my memory would be negligible it would be interesting to see if it was attainable just for the experience.

Hi Plec,

obviously there is no right or wrong with these things, some people prefere pure CPU GHz, others are system latency/bandwidth junkies etc, its all really Horses-for-courses i.e dependant on how the invidual uses his system.

I've had experience of the Intel® P45 Express and Intel® G45 Express chipset but sadly the Intel® P43 Express has eluded me so far. Is the latter chipset really not great for overclocking and tweaking then? I did a bit of reading into the Intel® P43 and couldn't see hardly any difference between it and the Intel® P45, main difference seemed to be the lack of Crossfire support on the Intel® P43 :confused:

Out of all the Intel® P43 I read up on the Gigabyte boards seemed to offer richer BIOS controls compared to an equivalent board from ASUS. I almost bought a Gigabyte P43 board but a used ASUS P5Q-E came up in the members market for the same £90inc I was about to pay for a new Gigabyte P43 Express so that was that (I speak semi-fluent ASUS BIOS heh!).

Anyway I think yourself and pastymuncher got it covered and I just wanted to make sure everyone was aware that running DDR2-1066 is possible in most situations if you can be bothered!

I think the Intel® Core™2 platform is still an excellant choice as you get a lot of power for not a lot of money. I have found to really get the best from this platform its well worth the time getting the system balanced, a combination of Processor GHz, FSB, System Latency and Bandwidth. In the limited (but thorough) testing I did gaming saw a nice increase in FPS *once* you removed the GPU bottle neck i.e System/Memory Bandwidth is helpful and should be pursued vigorously if your a Tweaker!

I think Ryan111 will enjoy getting to grips with his new hardware and by the time he is done tweaking the BIOS the end result will be better than an off-the-shelf preoverclocked machine could ever be! :cool:

Thanks for the comprehensive reply, Big.Wayne.

I think you summed it up pretty succinctly in that one paragraph. I suspect that my greed for raw CPU GHz probably side tracked me from balancing the two components more gracefully on my machine. I may have a tinker and just see if it's possible - as you mentioned the gigabytes BIOS are pretty versatile.

The E5200 combined with a good mobo is a great value base for a build - i bought one purely for the experience and intended on upgrading a few months later but i see very little reason to as it's doing everything i ask of it at present.

The great value of these components and their ability to achieve high clocks has really added to the overall fun of this build.
 
Hello all …
Now I have the same setup ( E5200 – EP43-DS3 – 4GB HyperX 8500 C5) I got it few weeks ago now. By mistake I’ve loaded default settings in the intelligent tweaker(don’t ask me why or even how I did it). I tried getting back the settings myself and this is what I have at the moment and :

System is stable and I’m happy with the speed of the cpu, just want to get the ddr2 to run a bit faster 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 system won’t start, it just keeps restarting itself … I’ve tried many different ways to do it (lowering 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 !!

P.S: Ryan111 what settings did you use to get your cpu to 3.5 and memory to 933Mhz ??
