Looking into buying myself a replacement Processor as I'm giving mine to my brother as his is blown. The 2 I found on UK sites were the 3800+ and the 4200+ both with the same cache sizes. I read up on test results on Tomshardware and other places and saw a high increase from my previous processor but a smaller one between these cards just over a 100 in the 3DMark 06 cpu test and just over 500 in the 3DMark 06 graphics test. My Rig in mind which should give me better bang for my buck? I heard the 3800+ can o/c from 2.0 to 2.6 which pushes its value I guess the 4200+ could do just as well in that corner though? The money difference between the 2 is £15 thats about $30. Anybody have any good links on o/c these cards? If anyone owns them how do the fans coup under stress? A replacement fan might boost the cost a bit.

My Rig at the moment -

Mobo - DFI LanParty UT NF4 SLI-D (Socket 939)
Processor - AMD Athlon 64 3700+ San Diego 90nm (Socket 939)
PSU - Ultra X-Connect 500W ATX2.0 Cable Detachable PSU
Ram - OCZ 1GB (2 x 512MB) PC3200 Dual Channel Gold GX XTC Series EL-DDR CAS2
HD - Maxtor DiamondMax Plus 9 120GB 6Y120M0 SATA 8MB Cache
Graphics - EVGA Nvidia GF 7800GT CO (Copper Heatsink) 256Mb DDR PCI-E TV DVI Vivo Fan 256bit

AS far as socket 939 systems, I have both the 4800X2 and the FX55 I use curently. I recently bult a 3800X2 socket 939 for a friend. The system is fine, but 2.6 GHZ. is stretching it. If you pan to overclock that far, you might just get the 4200X2 and save yourself some headache and money involved in cooling the system for that much of an overclock. Either processor is dual core and a nice step up from most single cores in many applications. Your choice. HTH.

Do you know any good guides to over clocking the 4200+ to stable performance? How far do you reckon I could push the card with the default heat sink and fan? Thanks

After you build the system, download the AMD dual core optomizer and processor driver here.

As far as a guide to overclocking the X2 dual core, read your MB manual as to what overclocking options are available in your MB's BIOS. Also install the latest BIOS from the MB's mfg.'s website. DFI's normally have great overclocking features if you can find the 'hidden' unlocks in BIOS. If you search these Forumz there are tons of overclocking info from past posts (go bac a year and half or more) concerning overclocking the X2's.

The Processor is OEM I found out so I took a look at the CNPS9700 CPU cooler. Both the NT and LED found a website that proved the differences -

Product Differences

Apart from the obvious colour difference between the LED and NT coolers the only real difference is how the fan is controlled. The LED is supplied with a standard 110mm 3-pin fan and a Fanmate2. The Fanmate is designed to allow the user to change the fan speed at will. The NT version is supplied with a 4-pin PWM fan that needs no manual intervention. The motherboard’s BIOS settings determine the fan speed which is based on the temperature of the CPU.

Never used a fancy bit of kit like this before. After looking at some tests using the fan it seems to run perfectly fine at the low settings 22 degrees at 37 db using a 150w test. So when I over clock my processor I don't think the need to have the Fanmate2 in my hand every 5 seconds is necessary, am I right? Any advice on these 2 fans would be good. Cheers

The Zalman 9700 is an excellent choice. I believe the 9700 comes in either a non LED fan version or an LED fan version. I curently have five of the Zalman 9500's running on my systems. I installed a Zalman 8800 yesterday on one of my micro systems. As far as the fanmate 2 that comes with the 9700, it is a switch that alllows the user to set the fan speed if so desired. When overclocking your procesor, heat will not become a major factor until you begin to raise the stock voltages to your chips and MB which causes excess heat. A far as overclocking your 2.4 GHZ processor to a 2.6, heat won't prevent you from doing so.

Thanks Badge for your help. Much appreciated I went for the LED.

Like I said, I have five of the Zalman 9500's running my systems currently. I added an 8800 Zalman a couple of days ago. I also have the Zalman Fatality installed in another system. I do not use the Fanmate 2 currently. I just run my fans at max all the time. I am constantly overclocking and making adjustments to my systems, so full speed works for me. Zalman provides some two sided tape to stick down the control in place inside the case if you decide to install it. The 9700 did well in the reviews I've seen and is one of the better coolers out there. My five 9500's are all LED. The 8800 is not. If you are building a low profile micro in the future the Zalman 8800 is just what you need as far as fitting in limited space and providing maximum cooling. Good Luck.

OP bought an OEM processor, but I do agree to just buy a faster processor and stop with all the, 'my temps are so high...do you think my 2.4 overclocked to 3.6 has anything to do with it?" I'm tired of reading it.

@ian141HT @ 4,DDR @ 333 & CPU @ 250 with the multiplier left @ x10 puts my 939 3800x2 at a stable 2.5ghz on stock voltages.

HTH
August 21, 2007 7:11:07 PM

The AC Freezer Pro will do just fine at cooling a 3800+ or 4200+ and is very inexpensive. I say, go with the highest CPU available as 939 is dead and CPUs will be harder and harder to find. Look for Opterons as well as they can sometimes be fond at a decent price. I could give you tons of US links for this stuff, but I know it wouldn't help.

In short, AC Freezer Pro and the 4200+
August 21, 2007 8:15:09 PM

I could only get my 3800x2 to 2.4 ghz stable at stock voltage. It was probably due to my MB (VIA chipset) not a temp limit or memory issue. I lowered the HT to 333mhz and the Corsair memory is right at 400mhz. Temps are 32 idle/<50 load with an Ultra X-Wind cooler. Both the 3800 and 4200 should OC to about the same speeds so I am not sure that you will be getting more for your money buying the 4200 if you plan to OC. The 3800x2 is more than adequate for most tasks at 2.4 ghz if you are staying with a s939.
August 21, 2007 11:44:50 PM

4200 is the highest I can buy in the UK for socket 939 unless I buy 2nd hand but I prefer not too. Looked at the Freezer Pro but the absorption latches on the Pro got a bad review by frostytech saying they were flimsy and expected them to have a short life span otherwise it is a good fan. I'd prefer something that is well built that I can use for a good few years and when I upgrade finally next year or so. If anyone has any links to a 4400 or higher I'd look into one of them but most have been discontinued or are out of stock.

I use a Zalman 9500 on my 939 rig because I love the look of the thing and it has it's own backplate which once fitted means it don't go nowhere.
August 22, 2007 12:15:52 AM

Have you looked at any opteron chips? They might be slightly cheaper, and they're a higher bin.
August 22, 2007 1:45:24 AM

buy the arctic cooling 64, and the x2 3800+. my setup is tforce-6100, 2x512 OCZ Performance, Antec Smartpower 2.0
the 3800 has no problem oc'ing, the max i can get is 2.94Ghz at 1.425 max temp is 52c. but if you can find an opteron for cheap i would go that route. also there is absolutely nothing wrong with the ac64s latches.
August 22, 2007 8:43:23 PM

I have used a lot of AC Freezers and they are great. I have one on my rig for a year and it still looks brand new. Under load, my highly overclocked brisbane was 10*C cooler then the OEM HSF at OEM speeds.

I got mine for $20USD shipped while the 9500 was $50 shipped. In no way would the zalman be worth it for your cpu
August 23, 2007 2:30:45 AM

I would have gone for the Pro but the website I bought my motherboard and cpu had a old version of the Freezer not the Pro so I have my packages now and I have the 9700. Thing is the Zalman website is down so I can't find out why my Fanmate 2 doesn't like to work with my motherboard or the fan; It comes on as expected normally until the first windows loading screen and goes off. I have managed to boot my system attaching the Zalman to the cpu fan socket on the motherboard directly. The only thing I didn't follow to the word on the instructions is the way the Zalman sits with the exhaust (non fan end) to the front of the chassis instead of the rear, but my case has good air flow from all directions and with a core temperature on speedfan v4.32 from 33 to 38c Idle it shouldn't hinder it. Maybe my Dfi rejects the Fanmate? I'm guessing my Zalman is set to silent or near silent mode because it's hardly making any noise compared to when it was booted up at the start.
August 23, 2007 5:02:06 PM

And while using just browsers to help me troubleshoot my brothers motherboard my pc reboot itself every so often. But I reckon that could be due to the low rpm of the zalman or something.

Athlon 64 X2 3800+ or 4200


I have a ASUS A8N SLI PREMIUM motherboard. It is a 939 socket motherboard does this motherboard work with any AMD 64 X2 Processor? Because I currently have a AMD 64 3700+ San Diego and am looking to get a dual core. I would appreciate it if anyone could get me an Idea on what to upgrade. I been looking at newegg.com and click on processors under the 939 socket category and I do not see any X2's. So i was making sure thwt X2's would work with my 939.

I'm new to this forum and havn't figured out how to create my own thread because it says to enter all required fields. I thought i did but it wont post. LOL
Thanks.

I believe the ASUS A8N SLI premium came out X2 dual core ready for the most part. I have had my 4800 X2 dual core running in mine. You can check on the ASUS website under your MB specs which BIOS is needed for the various 939 processors the board is capable of running.

get a 6000+ at 3.0 then you wont need to overclock
August 23, 2007 11:31:22 PM

I got the 4200+, from newegg, and because my old heat sink was almost two years old, I bought one form this guy, on ebay.

http://stores.ebay.com/JandLaur-of-Chestnut-Street

OEM Heat Sink CPU Fan Socket 939 AM2 Athlon X2 Copper 6000+

The total was 100.00, at the time.
I have OC it to 2.4 just fine. The benchmark jump up a 1,000 points.

Runs a 34 deg C unloaded and 40 deg C fully loaded.

go with the X2 4200+
August 24, 2007 1:38:05 AM

Zalman is still at 700-800 rpm. It should be 1250 - 2800 RPM +/-10% :pfff:  the fan keeps stopping every now and then too the fanmate2 has literally a 100rpm difference that's all and every time I try and change the fan speed while the pc is running the fan stops. what the hell? Anybody else had these problems with a zalman I updated my bios and found no effective changes I could make in order to stop this happening.
