So the CPU fan is automatically controlled yet there are no fan control options in the BIOS?, thats weird. As I said, there are no other options to control fans in BIOS. The automatic regulation of the CPU fan can be turned on or off, but that's it. If you have the time maybe you could verify if Sp...

1) But.. Isnt the numbers with the 7900GTX card and everything? I thought a very high power supply was needed for that.. not a 300W one. Well, a key thing here is that they didn't load the graphics card. This probably lowers the power consumption of their system by around 50W, compared to if the ca...

The Athlon64 Orleans (rev. F, Socket AM2) can go lower than 1.1V. I have this system myself and tried 1.0V @ 1.2GHz a few days ago. No problem.

I'm going to try for the lowest stable vcore at 1GHz, just for fun. I could report back here if you're interested.

Interesting, very interesting, thank you very much for doing that, that is a positive step in my view by AMD if it turns out to be true for all F-stepping procs, Vcore locks preventing downvolting are very much against what we are trying to do here at SPCR. :P No problem, glad I could help. :) And,...

Okay, I just tried to run the CPU on 1.00V at 1.2GHz (240*5). The results are pretty interesting... Check this out: http://files.upl.silentwhisper.net/upload1/1V.gif The voltage reported by SpeedFan and Everest actually varied slightly (as it "should"), while the CPU-Z voltage remained constant at 1...

I'm using this power supply with the following system: AMD Athlon 64 3500+ "Orleans" (Socket AM2) Stock AMD cooler on 5V Antec Tri-Cool on low Gigabyte GA-M55S-S3 (Nforce 550) 2GB (2*1GB) Kingmax DDR2-667 GeForce 6500TC 64MB (basically identical to a 6200TC) Soundblaster Audigy 4 Western Digital WD2...

Sounds good but I need to know a bit about the boards fan control features; BIOS level controls and SpeedFan support specifically. It has automatic regulation of the CPU fan speed and it worked well when I tried it with the AMD stock cooler. However, I wanted it to be even quieter, so I attached a ...

You don't have to worry at all! Only higher frequencies will cause instabilities and possible hardware malfunctions. Running the AGP and PCI frequencies on 64/32 MHz as you do now is actually slightly better for the hardware. You could possibly encounter stability issues if you go very low on the bu...

All the way down to 0.8V, but probably only to 1.1V on rev E/F CPUs, as usual. If it's not too much trouble, would you mind checking this (the 1.1Vcore lock)? It's a big open question at the moment whether the F-stepping has been given a Vcore lock; some people have reported that AM2 X2's don't hav...

Gigabyte GA-M55S-S3 (Socket AM2) Chipset: Nvidia Nforce 550 Cooling: Passive and pretty large Undervoltable in BIOS: Yes. All the way down to 0.8V, but probably only to 1.1V on rev E/F CPUs, as usual. Cool 'n Quiet support: Not mentioned in BIOS at all and it's not activated by default. I've been u...

it's caused by CPU, not the board. I have MSI Neo2 Platinum. On this board I can set Clawhammer chip to 0.85V by bios or software. But on 3000+ Venice E6 and X2 3800 manchester, it refuse to set below 1.1V by bios and software. somehow cpu can instruct board to set the voltage. Yeah, it's caused by...

If that is the case, then please explain why we only see this problem with E6 stepping CPU's. The number of boards which actually have undervolting settings in the BIOS is fairly low. Most of the talk about undervolting you see in the last year is using software like CrystalCPUID. This software sen...

Tibors wrote:The artificial limit of 1.1V is caused bu the CPU's not by the boards.

The limit can not be caused by the CPU, since it is the board that applies the voltage to the chip. Sure, the chips may not like sub-1.1 voltages, but the chips themselves can't stop us from applying said voltages.

Try downloading the manual and seeing if it mentions this feature. This is just indicative as features come and go depending on BIOS versions. Already did that. Nothing of interest... In case you aren’t aware, when you under-volt in the BIOS you lose the ability to change the Vcore dynamically us...

I'm pretty set on upgrading my system and I'm thinking of buying the parts below (I have the rest of the parts that I need): http://img246.imageshack.us/img246/2/compmf7.th.gif What I'm wondering about is the motherboard (ASUS M2V).

oldgeek wrote:Also that the present socket AM2 processors operating at 62watt are very low temp.will not get lower unless underclocked.

They'll of course run cooler if undervolted, just like any other CPU.

The test also need to include the system setup when CnQ and EIST kicks in. Listing a 3800+ (2.4GHz) with 4.64W power draw is misleading as it is probably running at 0.9V, 100MHz HTT x 5 mode. They give you the idle figures for both C'n'Q enabled and disabled (4.64W and 8.16W respectively). What mor...

So the stock clock rate on standard and EE models of the X2 3800 is 2.0GHz. So what was the article talking about here? Note that there is nothing extraordinary that Energy Efficient AMD processors appeared in the market. It is known that there is a linear dependence of the CPU heat dissipation on ...

They seem to have concluded performance per watt for us, but I was hoping to see actual benchmark/performance numbers alongside the power consumption measures to determine just where the X2 3800 stands. Excuse me? Aren't there enough X2 versus Conroe benchmarks all over the web? Xbitlabs did their ...

I recently aquired an 80GB 7200.9 PATA. Initially, it was a huge disappointment. The seeks weren't particularly loud, even when the drive was hard-mounted to the case, but the whine was unbearable. Although I didn't believe it would help, I ended up suspending the drive up-side-down on foam on the b...

Weird, the experiences I've read from other Seagate 7200.9 80gb users were that they were fairly (although not substantially) quiet. What date code and country of manufacture is stated on this HD? I don't want to open the computer right now to check the date, but the sticker on the bag said that it...

If you'd read some of our reviews on 3.5" Seagate drives in the last year or two, its noise would not have been a surprise. Note that there are NO 3.5" Seagates on our recommended list. Yeah, I knew that atleast some 7200.9 were noisy, but I've also gotten indications that the smaller PATA models c...

So, I finally got around to ordering a new drive for my old computer. I'm kind of regretting my choice of drive now, though... This Seagate has a very loud whine that can be heard from any spot in my pretty large room. It's that annoying piercing sound and it really pisses me off! :evil: Thankfully,...

I think some of you misunderstood me. I'm not changing to get more performance. I want to use the DVI input on my LCD, that's all. An increase in performance would be nice, but it's not like I'm going to have any real use for it in Linux anyway. Atleast not for games. I certainly won't replace the 5...

I have this Linux box that is really cool running. I use the following parts: AthlonXP Thoroughbred B @ 1GHz (10x100, 1.25V) Abit KX7-333 256MB PC3200 @ 100MHz (2.5V) GeForce4 MX440 SE (passive) The box has no case fans. The CPU has a small GlacialTech Igloo heatsink and the fan runs at something li...

according to the estimate on the extreme psu calculator it should be cooler than a stock A64 3200+ if you undervolt it to 1.1v... (ok I know that most A64's are way below the official max TDP, but it's still not bad) It will probably still use upwards twice the power of the 3200+. Still, at 1.1V it...

Well, that PSU is supposed to be pretty inefficient. Could be in the lower 60% range for this particular power load. That would mean a low 40W figure for your system components at idle, which is pretty okay. I don't have the possibility to measure my system at the moment and it's also an old undervo...

So, it seems to me, either the cores are different or the 59W TDP is, as a previous posetr suggested, a 'generalized' number. Yes, it is a generalized figure. Your Sempron 2600+ consumes around 30W with default voltage, so it's not even close to the TDP rating (which happens to be for the complete ...

Great! It's the 2MB cache version I'm looking at! And, no, I'm not in any particular hurry.

I've just built this very low power computer (from old parts) and I'd like a nice quiet harddrive to go with it. I have had two 7200.7 40GB PATA drives before and those were extremely quiet. No self diagnostic noise, no discernable whine and very soft (almost inaudible) seeks. All this without even ...
