PCTwin's 4 x HD 6770 Benchmarking Log

[PCTwin]

Four XFX HD 6770 1GB HD677XZHL graphics cards to play with on my Big Bang Marshall

My place of work bought five of these over a year ago for some of the office systems to run dual monitor setups

The fan noise proved a bit much for their quiet office environment and they decided these cards were too powerful for their requirements

So after a day they were packed back in their boxes and left at the back of the office for over a year

Of course, they can’t return them now; they are over a year old after all

They’re not exactly high end cards where they’ll sell quickly on e-bay

What to do??

Could sell them off in pairs for crossfire systems maybe?

Four of them in quad crossfire might work!!

And three for a triple crossfire leaving two for a crossfire setup is an option

Had to do it, didn’t I?

My first opportunity to put four cards together wasn’t going to slip away

Time for some pictures

You will have to excuse my use of flash photography but my camera died on me last month leaving me borrowing the wife’s e-bay camera

I’ll get a new one, just don’t know when

These are the first pictures I’ve taken of the new test bench so this is kinda like her maiden voyage on the forum

I will also take some close ups of the card at work tomorrow

Test setup

Motherboard: MSI Big Bang Marshall

Processor: Intel Core i7-2600K

Graphics card: MSI GTX580 Lightning

Memory: 16GB 2133 [RipjawsZ] F3-17000CL9Q-16GBZH (4GX4)

HDD: 2 x Western Digital Black WD1602ABKS 160GB in RAID0

Cooling: Swiftech Apogee XT rev. 2 CPU water block

Radiator: Swiftech MCP320QP

Pump: Swiftech MCP355

Power supply: Silverstone SST-ST1000P 1000watt modular PSU

Operating system: Windows 7 64Bit Ultimate

Normally the GTX580 Lightning would be in there, but today we have the four XFX HD6770 cards

The pictures on Scans website made me think this was a one slot affair, I don’t think so

Not a lot of room between them, but there should be enough

All setup and ready to go

The CPU is overclocked to 5GHz with a multi of 50 leaving the bus speed at 100 with a 1.48Vcore

As mentioned in my RipjawsZ review the CPU I/O is at 1.352v due to the memory so I left that alone

I don’t know yet whether to overclock the memory or not

Let’s get started

I will do some comparisons later, for now it’s just the 6770 setup

3DMark11 Extreme result : 2454 with a Graphics score of 2398..... wow

request OC a bit of it and test it on B3, skyrim and Metro 2033 bro and compare it with your monsta MSI GTX580 Lightning

thank you for sharing

luvly jubly boints

Hope so

Not many personal points as nobody has tested these in Quad or triple yet

hopefully some team points tho

Got a few scores to compare with this

 

[Rastalovich]

This is what benching means to me !

Get that unused kit and spank the pants off it like no-one else !

 

[marsey99]

thats ace that mate, love the new benchtable too

Time for the performance charts

3DMark11 Performance

That combined score isn’t a mistake

I have ran the benchmark a few times with different results but that’s the average

3DMark11 Extreme

The low combined score seems to be seems to be consistent with the 6770

The drop in Physics score also seems to be a common thing with the Crossfire 6970

3DMark11 Entry

Much the same outcome as the previous tests the Quadfire setup gets the best physics scores and the worst combined

The Crossfire setup even loses out on the Physics to the single card throughout all three

HWBOT Unigine Presets

The Basic benchmark seems to be a cruel test for the Quadfire setup considering it did so well on the Xtreme

3DMark Vantage Performance

Now that GPU score looks pretty linear to me

The overclocked crossfire pretty much rules so far but the Quadfire setup still beats the overclocked single cards

3DMark06

The Quadfire comes last in the SM2 score and loses out to the 580 on the entire suite

The 580 is not too far off the Crossfire score as well

Aquamark

The GTX580 and the Quadfire results were scored on a windows 7 install while the two 6970 results were scored on a windows XP install

The GTX580 runs like a snail in this benchmark with windows XP, I can’t figure it out

The Quadfire I haven’t done in XP yet

3DMark05, 03 and 2001SE

3DMark03 looks promising but I need to do an XP install to run some of the benchmarks

Going on to the overclock next, will do it then

 

[MSIRawZ]

Nice work!

 

[PCTwin]

Just uploaded the first overclock scores to HWBot

Will update the post later, gotta go out

Overclocking

The most I could get out of the GPU is 910 and 1280 out of the memory with the stock voltage

These 6770 cards are basically 5770 rebadged with most models coming with a locked BIOS

This means a very limited amount of overclocking as there is no access to voltage control

3DMark11 Performance

The overclock brings a general improvement overall though it still can’t reach the 6970 Crossfire setup

Another thing I note is the drop in Physics scores of the overclocked cards

3DMark11 Extreme

The same overall improvement

A break from the usual Physics results sees the Quadfire overclock get a small improvement

3DMark11 Entry

I’ve somehow lost this result, possibly I didn’t save it so I will get back to it

HWBOT Unigine Presets

The same as before and still a pitiful Basic score

3DMark Vantage

Still not enough of an improvement to get near the 6970 Crossfire

3DMark06

A drop in the overall score here, more tests needed I think

Aquamark

I am waiting to do the XP install before running this test

Until then I have submitted the stock score from earlier

3DMark05/03 and 2001SE

The same overall improvements with Quadfire managing to overtake the GTX580 in 05

HWBOT Scores

My HWBOT profile shows 10 submissions worth 62.4 points

This is a total of the (User) Global Points and the (User) Hardware Points

Total team points are 95.9 which is a total of Global and Hardware Team points

I am going to have to put a hold on this project for now

I plan on doing some game tests as well as the Windows XP specific tests

My brother has just turned up with a new graphics card for a system he is building for someone

An Asus HD 7850 DirectCUII

“You’ve got a week with it” he says

So I’ll be back on this in a week or so

Still got to do triple crossfire as well

Awesome review
