I845G outperforms I845E in every test!!!! which mobo has 845G ?

[gsethi]

hello

tomshardware new article shows that I845G is the way to go right now since it outperforms I845E in every test. It has all the features of 845e but also comes with DDR 333 support along with integrated graphics (for price conscious person).

well.....the question is, where to find I845G chipset boards. Earlier, i was inclined towards I845E (Asus P4b533-e) but now i will get the 845G board.

Thanks

i must have posted my thread right at the same time as you. anyways i find it questionable if the 845g is faster than 845e specifically if both are run at 166mhz memory bus.

btw if you do a search for 845g or 845e under motherboards on pricewatch, you will get a listing of places that sell all these boards. the nice thing is that 845g and 845e boards seem to be priced identical so it seems like 845g is a no brainer.

 

[gsethi]

yeah.....same thing i wondered before too.

if we run the 845e @ 166 and put in good ddr 333 memory and run that at 3:4 ratio, will that not outperform the 845g ?
even right now, 845e is so close to 845g. only thing it lacks is official DDR 333 support but wont running the FSB @ 166 make it the same ? i dont think that anyone on AT wants integrated graphics when we have GF3 and GF4s with us

i think that i will stick with Asus P4B533-e($170) or Abit BD7-Raid($140) or GA-8IEXP($145).

now gonna decide which one.

The 845G is not faster than the 845D or E. The only thing it adds is a 4:5 memory ratio. I posted this in GH:

Here is my take on 845D/E/G. Speaking strictly FSB/mem/overclocking features, the only thing the 845G adds is 4:5 mem ratio. The 845E doesn't add anything.

They stack up like this:

845D
Official support for 400 FSB DDR266
Unofficial support for 533+ FSB and higher DDR
3:4 mem ratio
Some FSB/Mem speeds
100 FSB 200DDR
133 FSB 266DDR
133 FSB 355DDR (need 3:4 ratio)
150 FSB 300 DDR
150 FSB 400 DDR need 3:4 ratio)

845E
Official support for 400 FSB DDR266
Official support for 533 FSB and higher DDR
3:4 mem ratio
Some FSB/Mem speeds:
100 FSB 200DDR
133 FSB 266DDR
133 FSB 355DDR (need 3:4 ratio)
150 FSB 300 DDR
150 FSB 400 DDR need 3:4 ratio)
Basically, exactly the same as 845D with official 533 FSB support

845G
Official support for 400 FSB DDR266
Official support for 533 FSB
Official support for DDR333
3:4 mem ratio
4:5 mem ratio
Some FSB Mem speeds:
100 FSB 200DDR
100 FSB 250DDR
100FSB 266DDR
133 FSB 266DDR
133 FSB 333DDR (4:5 ratio)
133 FSB 355DDR (need 3:4 ratio)
150 FSB 375DDR (4:5 ratio)
150 FSB 400 DDR need 3:4 ratio)
160 FSB 320 DDR
160 FSB 400DDR (4:5 ratio)

I assumed a DDR400 limit, since that is ~ the best that is currently available. The 845G will allow a higher FSB overclock without going over the DDR400 limit. For instance:
1.6A, 150 FSB 3:4 ratio DDR400 = 2.4 GHz
1.6A, 160 FSB 4:5 ratio DDR400 = 2.56 GHz.

It will be interesting to see what overclocking features each board mfgr makes available.

Are you sure that the i845G isn't any faster than the i845E. Unless I'm mistaken, in Anand's review it shows that the i845G running 133/266DDR is faster than the i845E at 133/266DDR.

 

[gsethi]

i think that now we have 2 reviews: anandtech and tomshardware: both confirming that I845G is faster than I845E.

It is faster at the same speeds (133/DDR 266) and even outperforms I850E(133/pc 800) in some cases. I think that i will go with the 845G board now. Integrated graphics is a plus but i dont need that though. That 4:5 memory ratio is a plus.

i think that I845G is the way to go now. here are some boards:

Asus P4B533-V
Giga byte GA-8IGXP
Abit BG7

Now, which of these boards are the best ? I am leaning towards the giga byte of the Asus but how are Abit boards ?

thanks

 

[THUGSROOK]

yea they said the SiS645 boards were good too....

 

[Sukhoi]

Don't forget the EPoX 4G4A+. It looks like it might be a really nice board.

 

[oldfart]

Anands review shows 845G faster than 845E/D. That changes things.

 

[gsethi]

personally, i dont feel like going SIS chipset side because i want stability too. Maybe because i am also an intel fan

hmm.....dont know about Epox boards. can anyone give me some reviews on them ?
I am personally looking for a board with RAID.

currently i have dvd, cd-rw, and 1 hd. going to add more drives making it dvd, 2 cd-rw, 2 hd, so i will need that raid setup.

i dont think that Asus is going to make a raid setup with I845G chipset. So that leaves:

GA-8IGXP
Abit BG7-Raid (if Abit makes one)
does Epox comes with raid ?

Thanks

 

[oldfart]

EPOX 4BDA2+ has been stellar. Best 845D board out there IMHO (and many others).

 

[gsethi]

that EPOX 4G4A+ really looks hot for that $130 price tag.
that is now on my list. only thing it lacks is the IEEE ports but for that price, you cant have all

GA-8IGXP will have everything but will be ~$150 since 8IEXP is $145 (845g costs $4 more).

now only if we could get some reviews for the Abig BG7...

 

[ForUmuse]

Somehow, I think all of you are nuts.

But, then again so am I!

But, how many of you are going to actually OC your stuff to this degree? By the time you spend for faster memory, cooling, etc., you could have simply bought a faster processer to begin with. Do you really think doing all of this is going to give you an edge in life? I don't think so.

 

[gsethi]

well.....it depends on you.

i have a 1.6a (cost ~130) running at 2.4 Ghz right now (costs 520)....saving $390 here.
samsung PC 2100 (cost ~55 last month ) running at PC 2400 speed (cost 55 now).....no saving here
heatsink.....using the retail that came FREE with my proc......no saving here.

so, aint i saving about $350 for a comparable system ?

i know that a processor plays a big part in overclocking but motherboard is the next big thing. A good mobo with a good chipset will give you added performance. Also....dont forget good memory. My processor can go more high but only thing thats holding me back is my memory. Going to get PC 2700 soon

thanks

The Epox 4G4A+ looks to be a real steal for the money. I mean, Really good sound (equivalent to the Cmedia Chipset!) almost like FREE Graphics. I know you guys want the Geforce 4 4600, but lets say u need a motherboard but NO graphics card yet, the onboard graphics is sufficient. 533FSB support, USB 2.0!!! RAID, LAN, DDR333, the works on top of that an INTEL chipset, hehe dont have to worry about incompatibiities.

Pros:
P4/Celeron
533FSB
5.1 Sound
Realtek LAN
Geforce 2 MX like Graphics
DDR333 (overclockable to use DDR400)
4X AGP SLOT
Plenty of PCI slots
RAID
$130 (same price as the KT266A Epox board when it came out, but this is a bargain dude)

Cons:
RAID (I mean how do people afford 4 MORE HARD DRIVES TO COPY the SAME DATA ON!!)
NO 8X AGP (WTH the new VIA chipset has it)

I know i repeated myself a few times, but this seems the board for me to Upgrade with, or else I'm looking for a AMD Hammer in the winter.. but Santa wont give me HAMMERS!!

 

[Sukhoi]

I don't consider RAID as a con as it should be able to be used as two additional IDE channels.

 

[gsethi]

well.....not 4 hard drives but 2 is quite common.
combine them with DVD drive, and couple of CD-RW drives and now you need extra IDE/RAID channels.

you know......when you get like 80 gb HD for only ~$30....you just cant resist...can you ? so thats where 4 HDs come from

 

[CoDerEd]

Abit BD7-Raid is less than $100 at NewEgg !!!!!!!!!
BD7II is $140 and IT7 is $157

BD7II seems like they have to give up some feature from BD7
like the built in debug card and reset/poweron switch onboard
and i'm not sure about the built in status LED though.

My next mobo will be the IT7 when i got enough resource about how well the OC.

Just wanted to add a bit of info here. According to Intel the i845E has one advantage over the I845G/L, namely the ability to use ECC memory (matters greatly to me, but probably noone else ).
As for DDR333 support in the i845G, since it isn't officially supported by Intel, who says it isn't a mere BIOS upgrade away on I845E based boards? I remember about two months ago I was laughed at suggesting that the new I845 revision would have any kind of DDR333 support...
Also, speedwise (i845E vs. i845G) I'd love to see a shootout between nearly identical boards eg. ASUS P4B533 vs. P4B533-V to see if there's more to the "i845G is always faster" story...
Just my 2 cents...

Oh, btw, here's Intel's comparison chart, just for kicks...

 

[oldfart]

But, how many of you are going to actually OC your stuff to this degree? By the time you spend for faster memory, cooling, etc., you could have simply bought a faster processer to begin with.

My setup:
1.6A $130
Extra cooling: $0
Epox 4DBA2+ $120
512 Meg Samsung PC2700 $150
Total: $400
Prices have come down since.

I run this @ 2.4 GHz, DDR400. A 2.4 GHz processor that could not be setup for DDR400 would be slower and a heck of a lot more $

 

[gsethi]

i am still not sure which chipset to get:

I845E:
Gigabyte GA-8IEXP - 145
Asus P4b533-E - 175
Abit BD7II-Raid - 140

I845G:
Gigabyte GA-8IGXP - 150
Epox 4G4A+ - 130
Abit BG7II-Raid ? - ????

suggestions ? i am leaning towards the Epox for its great value for price now. thanks to sukhoi for mentioning it here.

 

[WannabeDJ]

Quick question guys.. sorry for sounding like a noob... but I have 2 X 512mb PC2700 Samsung. I was planning to get the ASUS P4B533 - 845E chipset. Will I be able to maximize the use of my ram or do i need the 845G chipset that fully support DDR333? Thanks for the help.

 

[gsethi]

i am also going to get the Asus P4B533-E board now.....pretty sure.
i think that you should be able to use the Samsung PC2700. if you are going to overclock......your memory will already be running at higher speed.
100 fsb = pc 2100
133 fsb = pc 2400
150 fsb = pc 2700 (so if you are overclocking....you got perfect memory)
also, i think that you can use the 3:4 memory ratio to use higher memory. I am pretty sure that i will get PC 2700 with my P4b533-e board now.

i like this asus board because you can lock the PCI/AGP, you cant do that on Giga-byte unless they changed the BIOS. This one also has INTEL lan while the giga byte has realtek lan.

I think that i will also order this board this week and see how it works.

hope that helps

 

[oldfart]

also, i think that you can use the 3:4 memory ratio to use higher memory. I am pretty sure that i will get PC 2700 with my P4b533-e board now.

Better be careful on that. The P4B266 didn't do that, I'm not sure the P4B533 can either. I wouldn't buy it until I knew for sure. What are you looking to do? 133 FSB DDR333 (PC2700)? For that, you need a 4:5 mem ratio. the 845D/E doesn't have it. Only the 845G does. With a 3:4, 133 FSB = DDR 355 (PC2800+). If you can run 150 FSB, you can get to DDR400 (PC3200) with a 3:4 ratio.

With 1:1 ratio
100 fsb = pc 1600
133 fsb = pc 2200
150 fsb = pc 2400

With 3:4 ratio:
100 FSB = pc 2200
133 FSB = pc 2800
150 FSB = pc 3200 <---This is the one you want! You need 3:4 above 133 FSB to do this.

Any online vendors carrying these boards yet?
