Gigabyte GA-G33M-DS2R (Intel G33) breaks o/c record of Integrated chipset

[bluetooth]

Gigabyte GA-G33M-DS2R (Intel G33) breaks o/c record of Integrated chipset. It achieved 490MHz x6. Not only that it has the following features:

GA-G33M-DS2R comes with 1 PCIe x4, 2 PCI, 1 PCIe x16. As it has 2 PCIe slots with an open ended PCIe x4, you can run two graphics cards on this board in CrossFire mode too. This mATX completes with top notch features just like any full atx board. They include Realtek HD audio Codec, GbE PHY, TI 1394 controller. There are also 6 orange SATA II connectors supported by ICH9R. To its right is 4 DDR2 slots supporting DDR2-800 (up to 8GB in total). Below it is the IDE connector and 24 pin power and floppy connector.

One thing: In your review, you said one con was lack of eSATA.
Both I and a friend own this board, and it comes with an eSATA bracket (and cables). Unless that doesn't count?
Otherwise nice review.

Typo. I will get it corrected.

Running CrossFire on Intel G33 chipset
Yesterday we reported about the multi capable Gigabyte GA-G33M-DS2R mainboard. As this is an integrated mainboard which can o/c so well at 490Mhz x6. We thought it might be worth while to test its CrossFire capability since there is an open ended PCIe x4 slot.

We ran a E6300 and a pair of 2600XT on it and benchmark it using Catalyst 7.7. With no CrossFire enabled , it scored 8959 marks. With CrossFire enabled (Dual 4x since the slots are 16x and 4x), it scored 11,211 marks, giving it a boost of 25%.

Gigabyte GA-G33M-DS2R o/c to 356 X 9 == 3,200Mhz on stock Intel AIR cooling; using the Q6600 2.4GHz B3 processor; Vcore level is set at 1.331v, which droops to 1.264 idling, and droops further to 1.248 loaded; DIMM at 1.9v (stock); the others voltages are at default levels. DDR2-800 is operating at speed of 3x356 = 1068MHz, 5-5-5-15. Temps 32c idle, to 60c with all 4 cores 100% loaded, totally dependent on room T-ambient. Operating with the onboard GMA 3100 graphics processor.

CPU GTLREF Ratio Control (fsb signal overshoot margin) at 0.636. If anyone has diddled this for good or ill, let us know. I thought 0.603 was better but that is iffy, maybe imagined.

At max with all four cores loads with OCCT v1.1.1 the sys does not run very long. If I raise Vcore it runs okay but then I get hooked by temps. When torture testing, stock Intel cooler ain't good enough. Gotta fix that.

My COOLER MASTER 92mm Hyper TX2 CPU Cooler sucks, could not get it seated properly, although I ran it for a couple days and then it fell off. The Intel (copper core) heat sink seated firmly and easily; it has noticeably more precise and robust push-pins.

Really beautiful motherboard. I've tested my Ulead Video Studio edit (DVD movie) rendering which runs ~50% faster. Now I can run two-pass, higher quality processing in less time than single-pass previously.


Of note -- To assuage the fear and tremors engendered by the idea of temperature, I found Intel's datasheets, especially for thermal data. It's interesting that they show charts and graphs for Tcase, not Tcore as I would have expected; therefore, Speedfan v4.33 temps are adequate and appropriate for testing, although Core Temp v0.95.4 is wildly interesting. I had been bemoaning my bad luck when I received a B3 105W Q6600 rather than the G0 95W revision. But if you look at the specs, the G0 runs hotter than the B3--HA!--even at idle. (Of course your test data may differ.)

Info. Does anyone know for sure what Speedfan v4.33 Temp1 and Temp2 are? on this mobo with this processor.

Another note. Look at http://www.newegg.com/Product/Produc...82E16820208329 for these nice DDR2-800 Transcend AxeRAM 2x1GB PC2-6400 cheap cheap. Running effortlessly, I think.
