E4500 HTPC first time overclock

post #1 of 18
Thread Starter 
Hi

Need a bit of help here on which direction to go as I'm driving the wife mad by working on this rather thasn letting her watch Desperate Housewifes!

Got a e4500 in a Asus P5G41C-M LX micro ATX with 4gb of DDR3 1333 (9-9-9-24). As the FSB is limited to 800 on the CPU the Bios has underclocked the RAM accordingly and I cant change anything there. It shows like this just now:
Memory Timings 6-6-6-15 (CL-RCD-RP-RAS)
Command Rate (CR) 1T
DIMM1: E30107A 2 GB DDR3-1333 DDR3 SDRAM (8-8-8-22 @ 609 MHz) (7-7-7-20 @ 533 MHz) (6-6-6-17 @ 457 MHz) I can get her up to about 2700 by raising the FSB to 249 but after that she wont post. Using a lower multiplier gets me nowhere either.

Question is where should I go from here. Is the RAM limiting getting up to the 3000. (I had DDR2 800 in there but Bios doesnt let me go below 667 -confirmed by manual) Any help would be appreciated!!

No takers huh? Maybe I should just save up for a core i3 cpu and mb...

Well I managed to now get a cpu fan error on the cooler and broke the plastic surround while taking it apart. Add that to the Artic Freezer cooler that I had originally bought that didn't fit (I sawed it to size only to realize that those copper tubes are sealed for a reason..) so its back on to the intel cooler as the boss wont let me break another...

HTPCs arent meant to be OCd. It defeats the purpose of being able to keep them silent while cooling the cpu. If I where you, let your wife get back to her shows before you are cut off, LOL. Then just look at either the i3, or even better, a Sandybridge. Maybe even add some more storage and a tuner card so she can use it as a DVR and record some shows. Bet she will love ya more for it.

I know your right, but I got it in my head now!!! We never really record TV and the micro atx pci slot just starves the 5670 of air so the tuner is in the drawer. And more mce menu items will just confuse her...
Anyway when its doing video playback the 5670 is doing all the work and the CPU is at idle and I've got a hardware fan controller in there so I turn them down to next to nothing (and the volume up) so it doesn't bother her much (as long as showrss hasent missed any of her shows ). When I have a bit of free time, the fans go up, services off and the HTPC transforms into super budget gaming rig playing GTA at 720 on the TV (not at high settings ) , hence the reason that I need a bit more power!

I have the same board. You know you can change the ram multi right?

You only get like 2 options though. I have a celeron e3300 in mine. Have it oc'd to 3.0ghz cause I felt it needed a little more power. The board is pretty weak as bios settings go. So the ram speeds you see are what you get.

249 fsb is pretty good I wouldn't expect much more. I see you've had ddr3 running in it. I have ddr2800 in it and tried and tried one day to put some 4gb ripjaws I had lying around.

Damn thing would never post so I finally gave up.

Yeah, with the DDR2 (which I now dont have) it allowed me to change between 800 and 677 only. With the DDR3 it locks me to 800 (the cpu fsb speed). I guess that the board is the limiting factor then here cos I thought that . My DDR3 just booted up perfectly and at 36Eur for 2x2gb I shouldnt really complain and it will do for the next build.

Really think I should do some more research into the boards oc capabilities before buying stuff in the future.

Yes you should

There is a way you could OC the CPU by quite a lot, but read as much as you can about it, it's called the BSEL mod. OCN has a pretty good guide on how to do it:
http://www.overclock.net/intel-cpus/...mod-guide.html
Basically using a conductive pen (Fry's usually have) you draw a line on the processor between different pin-pads. With this you change the base FSB from 800 (your case) to 1066 or 1333 while keeping all the rest of the parameters at stock. You can also overvolt in case the processor isn't stable at those speeds.

Just remember to reset your BIOS before doing this. After you do the 800=>1066 FSB mod and the 1.4V (which is likely to work) you can try to further up the FSB from the BIOS from 266 to whatever is possible within 1.4V or before the RAM limits you again.

Cheers, hope it works.

Excellent - back in the game

Will save some pennies first for a cheap upgrade just in case I fry somthing.
(i3560 or PhII 955x5BE I'm sure a search can cover that one...)

Hmm, now to find a conductive pen in Spain

This is the best mod out!!!

OK so spent the last few days trying to find conductive pen. No joy. Finally in a car garage I got some of their 10 year old conductive paint for window heaters for free. First got out the office PC to test (e2200) and tried without any luck. Then realized that I should read the instructions and "Shake well before use". 10 mins to dry (1067 mod) and boom, 2.93ghz on a 3 year old 300 euro Dell vostro!!

So am about to do my e4500 and with my calcs:

1067 Mod = 1067/4*11=2934
1033 Mod = 1333/4*11=3665

So which one should I go with, do you think that it would even post at 3665 allowing me to drop the fsb in the bios or should I just do the 1067 and then try and push the fsb up to around 3000? (I would try both but it takes me about 1.5 hours to rebuild my HTPC especially the DIY Heatsink and fan and cable ties..)

Cheers!
