DFI - NF4 UT-D Normal upper HTT Limit?

[Phlargo]

I've tried multipliers as low as 4.0x up to 9.0x and I can't get past 288 for my HTT. I also have been cutting my memory multiplier to 1/2. I've heard people talking about 330! Also, I've been able to get my CPU stable to about 2.57 ghz and memory to anything under 200 mhz. Any ideas about what might be causing my limitation.

I've tried upping CPU Volts, Northbridge, and LDT. Nothing.

I've got my LDT Multiplier at 3X.

Note: I'm using the Antec Sonata's 380S True Power PSU - it's only 20 pins.

I suppose another question is: Would my power supply be limiting my total cpu overclock speed? I can get into windows at 2.62 ghz, but it freezes/reboots as soon as I fire up Prime 95.

I'd hate to buy a new power supply when I just got this one.

My CPU's a 3200 Winnie

I had the same problem with my mobo, I can't get past 288 (exactly) with a 9x multi regardless of how loose I make my mem timings.

It's probably the PSU. A 380W True power isn't very strong for heavy overclocking on a s939 platform.

 

[Phlargo]

But it overclocks pretty well anyways on the CPU.. I'm really talking about the HTT only - you think the power supply is limiting the HTT overclock? What I'm really asking is: Where is the stress? Is it the power draw on the CPU? Does the HTT overclock rely on extra CPUID voltage?

Check your rails at prime95 load with speedfan.

 

[Phlargo]

Oooh.. Speedfan - I wish that was a name I had seen before. That'll provide the Amps that are going through the rails?

I've already got Smart Guardian running and I've never seen any of the gauges dip far below its stated voltage in my overclocking.

 

[Phlargo]

Hmm.. downloaded and installed SpeedFan.. but I still can't see how many amps each of the rails is producing... am I just not looking in the right place?

 

[JMWarren]

Just so you know DFI Recommends a 480w PSU thats 24pin. I've seen people on DFIStreet state that this is pretty important.

Speed fan won't tell you how many amps your comp is drawing, it will only read the voltages. If they dip a lot under load, you definately should get a new PS.

When OCing my winchester on my ultra-d, I raised the HTT to 300 and it booted into windows, however I never tested it that high because my CPU topped out at a HTT of 268 (2412 mhz).

the best way to measure your voltage is to get a multimeter and read it directly from the psu via the power adapters you use to plug into your harddrive, cd drive, etc...

the red is the 5 volt rail and the yellow is the 12 volt rail...

never trust the bios or any other readings at that...

i've seen programs report my 12volt rail as low as 11.8 when it was at 12.2+

.... back to the issue of htt

what ram are you trying to use? tccd? bh-5? utt?

Ah yes.. this is an issue. I'm actually temporarily running on an old single stick of Corsair Premium 2700 while I await my RMA for my OCZ VX Value (I should get it tomorrow and then a lot will change)

As long as I keep it below 200 mhz and at CAS 2.5, it keeps quiet. I figured that, given that, and forced settings when HTT is at 289+ (3, 4, 4, 8) it should have no trouble keeping up. I've considered this to be a limitation somehow, but I figured the mem divider would take care of this and keep memory limitations out of the equation.

For additional clarification, the specific problem revolves around specific the stage of the boot where it lists which devices are at which address. It gets down to the APCI Controller but never shows the "Backing up BIOS" and then just does a restart after a short pause.

When messing with CPU overclocking, I noticed this symptom when I was 'pushing' the CPU too hard with insufficient voltage. Consequently, I've tried to raise the voltage on my CPU but the result is the same.
