Does CH5 like volts?

[Çhrist0ph]

Does CH5 scale ok with more voltage?
I have OCZ PC3200 EL which im guessing is CH5. Ive got it running 2,2,2,3,5 @ 220 mhz (2.7v). But I cant get anymore mhz by upping voltage. BUT, ive only tried as high as 3.0V. I have an infinity that can do vdimm up to 3.3V, should I try to go higher with 3.0+ volts? or will it kill my ram?

[skate2snow]

My CH5 do everything i whant w/ 3.3V:p:.

But if a jump from 2.7V to 3.0V didnt give you 1MHz i doubt they can do more:(

[Mrk200]

I seem to gain about 4-5 mhz for every .1 increase in voltage on my 2x512 twinmos ch-5.

[xDUCK]

If you can't go a single mhz higher no matter what the voltage, it's probably your motherboard holding you back, not your RAM.

[Çhrist0ph]

i doubt its my mobo,the infinity is slowly establishing itself as one of the mainboards in the OC dept.

but what if i loosen the timings? What timings would be ideal but not so loose it defeats the purpose of gaining a few more mz's?

P.S. Im not even 100% sure this is CH5, I only got it about 2 weeks ago and I heard OCZ is using some new IC's that are different.

[TheWeaseL]

The only way to know for sure is try. I've never heard of anyone killing their ram by throwing 3.3v down it for 5 minutes...Not to say it can't happen, nor am I responsible for what you do, but you will only know if you try.

[Vlad Draculea]

i even heard because i am not completely deaf.

[Çhrist0ph]

well, I tried 3.2v, but...

I forgot to turn down the multi after i upped fsb/ram to 230, windows tried to boot at 2415 mhz and now my HDD is corrupted:(

Now, no matter the clock speed, after I get to the windows loading screen, all i get after that is a blue screen saying a registry file is missing/invalid/corrupted

I now have to wait to get ahold of another HDD to load winxp onto so I can backup all the important stuff off of my SATA HDD before I format it.

[Çhrist0ph]

Just took off the heatspreader on the ram, it is winbond CH5.

You don't have to format it, you can repair the registry.:stick:

[Çhrist0ph]

Oh god that would be awesome!

Please tell me how to do that.

[Techmasta]

Insert your windows xp disc. Press enter to install and then press r at the partition screen to repair the installation. It will go through the normal windows setup but all of your files and most settings will remain intact.

There is a good lesson to be learned here....The safest way to test out your overclocking is from Windows using one of the Windows based overclocking tools (8RDAvcore is good)...That way, if you lock it up, no damage will be done to critical Windows files. Once you find your maximum stable setting in Windows (use Prime95 to test) then set it in the bios.

As xduck said it should be possible to do a registry repair from the 'Repair Console' that you can bring up from your XP boot disc...
Note this should NOT involve going through the full installation again as Tachmaster indicated...You would only need do that if the 'Repair Console' option failed.

[halcyon]

I believer most of the registry damage comes from oc of PCI-bus related integrated SATA controllers not working correctly (even if the PCI bus is).

Prime95 testing won't help in that department, although I definitely recommend it otherwise.

So, is there a safe way to test overclocking and say, SATA corruption issues, inside Windows XP?

[Çhrist0ph]

well, i should be done re-installing winxp and re-installing all progs in an hour or two.

then i'll try to get my ram up to maybe 230 or so w/3.2-3.3. Ill be back with results soon

i hope taking off the heatspreader should help some too.

[Çhrist0ph]

now doing 230 mhz @ 3.3v (cas 2.5,2,3,3,11) 1:1

:)

[xDUCK]

Most of the time, booting off a different Windows installation will solve it for me. I don't even have to do anything, it somehow knows the other HD is corrupted (I assume it's using a checksum), and repairs it.

[pelikan]

When I'm pushing the FSB I boot into memtest86 and make sure it will pass test 5 before loading windows. If it will pass test five windows won't get corrupted. This is, of course, for pci locked mb's only.

Not in this case...his board has a locked pci bus...The corruption is simply down to the cpu and memory making errors due to too high an overclock.

Does CH5 scale ok with more voltage?

I am running my TwinMos SP (I guess it is CH-5) @250mhz (3.5V) (2-2-2-5) on my DFI NF4 ultra-D. I can boot into window @255mhz @ 3.5V. But I can't boot into window @ 260mhz no matter how much voltage I supplied to it. (3.6v, 3.7v,3.8v,3.9v and 4v are failed to increase even 1mhz).So, I think, my TwinMos has reaches its limit. But make sure you have actively cool your ram. For my case, my RAM is warm but I did not actively cool it. If you're worried that extra voltage might 'kill' your ram, you better cool your ram as your ram is different than mine and there is not guarantee in oc that your result will be same as mine. Hope this will help.

Uh... This thread is from January 2004, you know :stick:

[[timko]]

Nice thread dig :slobber:

Anyway, I've got some old 2 x 512Mb Corsair 3200LL rev1.2 CH5 that easily does 245Mhz 2-2-2-5 1t @ 3.3v on my DFI NF2 board. These things should fly quite nicely once I get my DFI NF4 mobo :)

[Bennah]

I had some OCZ 3200EL back in the day. Rated @ 2-3-2-5.

With volts then flew. Had them upto 252 2-3-2-5 w/ 3.4vdimm back on the infinity with a good ol' AXP-M... ah they were the days :D

[afireinside]

Damn you person who bumped this thread :( I was like "christ0ph and xduck!?!? havent seen those guys in forever!" than I saw the post date...

[kromosto]

this is like history channel :D

[saaya]

hey, this thread doesnt really belong in the xtreme overclocking section wich is for xtreme overclocking topics only, i moved your thread to the xtreme bandwidth section wich is for all memory related topics :)

my ch5 didnt scale much above 3v ... was a lil odd...

[FiNcH64]

indeed i guess some ch-5 do like high voltages (like mine hehe) my pair of mushkin level one pc3500 1gb kit, can do some nice 260 mhz 2 3 2 6 at 3.45volts on my lanparty sli-d hehe.. and it seems it can go further but not need now, cause my crappy winchester can't do more than 2.6 ghz on air :woot: :(

but i was impressed with my ch-5 mushkin :slobber:

mushkin just damn ruless :banana:

and 2 2 2 5 ?

[AMD-me]

This is how my CH-5 (in my FS thread) is scaling
217 2.7v
231 2.9v
240 3.1v
247 3.2v
249 3.28v
256 3.4v

Any volts higher than that cause errors.

[ozzimark]

wow, this thread started back in 04 :eek:

i have some CH-6, real old stuff.. it only does ~235mhz at 1.5-2-2 with 3.2v, more voltage causes errors :(
(but then again, i kinda broke the ram stick, so that might be causing some issues)
