Excluding this Elpida sales for August, revenue was up 16% quarter-on-quarter, driven primarily by an increase in DRAM ASPs for the second consecutive quarter. DSG gross margins were in the mid-20% range, up about 1% from our third quarter. Keep in mind the Q4 and Q1 DRAM gross margins are and in the near term will be negatively impacted by the flow through of Elpida's inventory which was written up to market value at close as Ron described in his purchase accounting comments earlier.
We achieved record bit shipments in all of our premium DRAM segments with the non-PC business representing about 55% of our gigabit shipments in the quarter. We shipped over 300 million gigabit equivalents into the server DRAM segment in Q4 driven by strong demand from our data center customers and cloud service providers.
For fiscal 2013, this is a 53% year-over-year increase in bit shipments which represented a 13% increase in revenue. We had a record quarter in our networking business for both bits up 5% and revenue up 8%. RLDRAM shipments set a company record as we are seeing a strong demand from Tier 1 OEMs, as well as through our distribution channel.
We also had a strong quarter in our consumer graphic segment, which continues to be an attractive premium market. Bit shipments were up 38% quarter-on-quarter and we expect strong demand in Q1 and particularly I'm looking forward to the upcoming launch of next-generation gaming consoles for this holiday season.
Elpida's GDDR5 technology rounds out our portfolio in this fast-growing segment. On the technology front, we recently announced our Hybrid Memory Cube interoperability with FPGA platform from Altera, a major milestone for us in this new solution for the high-performance networking and computing segment.
In addition, our RLDRAM III product continues to receive strong market endorsement form out Tier 1 networking customers. We are seeing strong yield improvement in our 25-nanometer process technology and will continue to ramp this technology through fiscal 2014. We are also on track to introduce our 20-nanometer technology beginning in the second half of calendar 2014.
Overall the DRAM market remains tight, given growing demand in the specialty markets and under supply in the PC DRAM business and the impact on supplies from the Wuxi accident inventories appears extremely low across both our OEM customer base and at distribution channel.
We are on allocation with customers on multiple segments. OEM contract pricing while increasing continues to lag the rising spot markets. Our specialty business typically lags the market in terms of price movement but we are seeing increases across these segments as well. We are optimistic that the DRAM market will remain strong through the end of calendar year 2013.
When you include one month of Elpida's mobile business, revenue for the Wireless Solutions Group was up 70% quarter-over-quarter, coming up for Q3, the revenue was up roughly 30% from the prior quarter. Without the Elpida impact, revenues for WSG were flat quarter-over-quarter as we were able to redirect some capacity to higher margin opportunities in computing. Q4 gross margins swung from a negative 4% to a positive 8% in the quarter.
