SD 3700 on Vapo LS craps out at 2.6ghz???

[bubblethumper]

Ugh. Here's the deal:

510-3 bios
NF4 Ultra-D
VapoLS

System can't seem to get past 2.6ghz. Stock voltage or higher. I tried lowering the memory speed, but it didn't help.

Anything else to try? I'm mega-disapointed. Maybe I'm just too inexperienced with AMD chips, but this is rediculous. People are getting to 3ghz on air and I can't even get past 2.6 with a vapochill!!!

Any help would be greatly appreciated.

Note: If you happen to remember a few posts I had about my last SD3700; this is a different chip and without cold bug.

[afireinside]

You have lowered the HT/LDT multi to 3x from 5x correct? Whats CPU Vcore?

Dude you have the same cpu i do . i cant get past 2.65 gighertz on my vapochill LS and i cant use any of the multis besides 10 x 260

its a 0512xpmw

ordered it from crapmonarch

[CandymanCan]

:bs: that sux dude

[AMD-me]

My bet is HT multi, the crap out point sound about right.

[perkam]

lol....both of are using TCCD ;) Use some UTT/BH and you'll get higher.

hmmm... i'll throw some other memory in there to troubleshoot, but I'm thinkin' it's just a crap chip (making this my second bad San Diego). I'm running loose timings and tried underclocking the ram (which didn't help).

Sigh

It's a greater probability that its a technical obstacle than anything else....there has yet to be a BAD SD...considering many are now being speed binned from FX-55 line...not very likely at all.

Try some non tccd ram.

I like that name lol
Maybe they should rename it :D

I have used redline ram and all different types of bioses. SO LOL

I think my next cpu is going to be the x24600 or x2 4800

Ecoding a dvd i 12 min sounds mighty fine where as my fx 55 at 3.3 gighertz is like 35min.

[HousERaT]

Sorry to hear that bro..... that's one of the worst clocks I've seen on a San Diego using air. Even worse for a Vapo...... I wonder if it could be mb related?

[Eldonko]

Dump it on ebay and get a new one :)

[Absolute_0]

Yes, and hope for higher clocks in the future :toast:

[ewitte]

Thats about where mine craps out without further BIOS tweaking. I've been able to get it stable on water at 2.8Ghz after playing around a little. Kinda crapy that you have a VAPO and would have to go through a lot of tweaking that early though.

[DilTech]

First, ALOT of SD's HATE the 10x multi, I can't even do 250x10 with my SD, but I can go about 250x11 with 1.525V. The 10x multi is VERY wierd on SD's, it's hit or miss, some will NOT function without ALOT more V's than it'd normally take and others will handle it fine. I'm bettin you just got one that won't take it... With mine, if I put on the 10x multi and try 250 or higher, my wireless network card craps out WITH the pci-lock enabled. I know it's the multi, as I can do 9x299 FINE(my gigabyte board won't go past 300) without issue... Switch to 11x.

Try switching to the 11x multi, go 236x11 and start from there, it should handle it fine. Also, set your HT Multiplier to 3x if you haven't already. Also, try kicking up the chipset voltage a notch, and see what happens. It seems to work for some people.

[bubblethumper]

Ok, well somehow I missed the setting for HT and dropped it to 3x. This gets me up to about 2.7ghz. Until I get things sorted, I'm booting the memory at 133mhz and then use clockgen to OC it.

I'll go try to up the chipset voltage and see what that gets me.

Grrrr.... Intel on vapochill was such a breeze. Almost makes me wanna Pentium D it and be done

Edit: I'm running default Multi. I don't want to tweak for mem speed until I get a rough estimate for the processor speed ceiling.

[AMD-me]

I was right :D

[Absolute_0]

OCing AMDs isn't too hard. I got to 2.8 Ghz within half an hour of installing windows
loosened ram timings, set AGP to 67, HTT Multiplier to 3x, FSB 280
i went 220, 240, 250, 260, 270, 280.

I can understand missing the HTT multiplier if you're used to Intels though.

[bubblethumper]

Ok, chipset voltage bump is getting me up to 2.9ghz. Craps out before 3ghz. If I can't find a way to get this setup to perform better than my old s478 intel setup, then I'll go back there temporarily

Be patient, you've gone up 300 Mhz in the last little bit. Plus a Sandy at 2900 Mhz is nothing to balk at.

What voltage are you currently at?

[AMD-me]

IMO 64's are much easier than my Xp-M

[shadowing]

Btw, try out air. It may yield higher clocks. OPB's did higher on air than phase shift. I think lower temps allow overclocks, but no higher voltages.

[bubblethumper]

voltage doesn't seem to do much. I'm up around 1.65v

As far as trying air, well, I only have water cooling and phase cooling. I ditched air cooling a LOOONG time ago and don't have a heatsink to attach to it.

[ben805]

bump up your vcore to about 1.7~1.75, max out your LDT and Chipset voltage....stick with 11x multiplier and 3x HT, if you still can't get it over 3.0G then you can either sell it on ebay, or take off the IHS and try again!!

Done. Still wont do 2950mhz 1M superpi stable (which isn't saying much)

This thing still doesn't outperform my Intel chips. Ugh

[HousERaT]

Guess maybe it's not the best chip in the world. What's the stepping?

What do you have the Intel systems clocked at? I'd guess you need about 4.2-4.4Ghz to outperform 2.95 on a San Diego. Except for MM benchmarks.

[bubblethumper]

My 3.4C was clocked at 4.6ghz. I also have two different 3.2 prescotts, one a CO and the other a DO which both go to somewhere between 4.2 and 4.4.

Now, my San Diego is barely 1M Superpi stable at 2.95 where my 3.4C was completely stable at the speed i mentioned above.

I dunno what to do. Ebay it? Then what to buy? This is my second SD3700. First one was defective. Second one OCs like crap. I'm kinda gun-shy after two bad SD3700s. I don't want to leave s939 after migrating from Intel.

Venice 3500? Clawhammer 3500? (Dare I say it), Newcastle 3800??

Impossible!!!! It's either board can't handle high HTT or mem is crapping out.. You need to isolate those first!

Aren't I isolating the ram by underclocking it? Should I really gank out my old kingston hyperx from another machine to troubleshoot?

Also, I tried droppping the HTT multi to 2x to see if that improved things (it did not). Isn't that also isolating the potential issue with HTT?

Edit: THANKS FOR THE LINK!!! My problem may be the SATA plug i'm using crosses fingers

[Zebo]

Depends.

1. You should isolate ram by overclcoking it after you find max HTT which it will not exeed... when doing this set CPU multi to 6 or 7 to eliminate it from equation.

2. Isolate max HTT should be step #1, while keeping ldt x HTT around 1000mhz so you may have to change LDT ratio as you increase FSB/HTT. Also you rule out ram here by setting mem setting to 100 (or half HTT speed). And you also rule out CPU with multi to 6 or 7...

I'm not familiar with Phase change, but that CPU should be doing 2600Mhz minimum on AIR!!! Let alone super cooling. Follow the guide step by step... You should get results. Gluck:)

[bubblethumper]

Cinderella update (since it's getting close to midnight) ;) :

SATA port seems to be the problem!!!!!!!!!!!!!!

Problem solved!!! I'm easily at 2.8ghz on stock voltage now. WOOT!

Now I can see what she'll really do!

THANKS!!!!!!!!!!!

[Zebo]

Hehe you saw that part about SATA eh? Something so simple yet so fustrating...

[bubblethumper]

Doh, hold on a sec. May not have solved it so easily. Changing SATA port has helped majorly, but only for stock volts.

Stock volts or 1.7, I'm still stuck at 2.9ghz

BTW, the methodology in that link is pretty much what I use for OCing

[bubblethumper]

Ok, i'm serious this time: Problem Solved

Turns out the mem dividers are crap. I switched to 1:1 ratio and now I'm cruising past 3ghz. 3.15ghz so far.

[ben805]

just be patient and try every possible tricks you can pull out of your sleves, with the right combination of settings you should hit 3.2 but be happy even if you can only do 3.1 prime stable....3.2~3.3 if you're lucky. :D :D

[bubblethumper]

Yeah, I'm still working on it, but I'm going to be happy with anything over 3.1ghz.

So far, 3.2 looks to be good (and seems to be typical for phase change)
